NAME
       xterm - terminal emulator for X

SYNOPSIS
       xterm [-toolkitoption ...] [-option ...] [shell]

DESCRIPTION
       The  xterm  program  is	a  terminal  emulator  for  the X Window System.  It provides DEC
       VT102/VT220 (VTxxx) and Tektronix 4014 compatible terminals for programs that  cannot  use
       the window system directly.  If the underlying operating system supports terminal resizing
       capabilities (for example, the SIGWINCH signal in systems derived from 4.3bsd), xterm will
       use the facilities to notify programs running in the window whenever it is resized.

       The  VTxxx  and	Tektronix  4014 terminals each have their own window so that you can edit
       text in one and look at graphics in the other at the same time.	To maintain  the  correct
       aspect ratio (height/width), Tektronix graphics will be restricted to the largest box with
       a 4014's aspect ratio that will fit in the window.  This box is located in the upper  left
       area of the window.

       Although  both  windows	may  be displayed at the same time, one of them is considered the
       ``active'' window for receiving keyboard input and terminal output.  This  is  the  window
       that  contains the text cursor.	The active window can be chosen through escape sequences,
       the ``VT Options'' menu in the VTxxx window, and the ``Tek Options'' menu in the 4014 win-
       dow.

EMULATIONS
       The  VT102  emulation  is  fairly  complete, but does not support autorepeat.  Double-size
       characters are displayed properly if your font server supports scalable fonts.  The  VT220
       emulation  does not support soft fonts, it is otherwise complete.  Termcap(5) entries that
       work with  xterm  include  an  optional	platform-specific  entry,  ``xterm,''  ``vt102,''
       ``vt100''  and  ``ansi,''  and ``dumb.''  xterm automatically searches the termcap file in
       this order for these entries and then sets the ``TERM'' and  the  ``TERMCAP''  environment
       variables.   You  may  also use ``vt220,''  but must set the terminal emulation level with
       the decTerminalID resource.  (The ``TERMCAP'' environment variable is not set if xterm  is
       linked  against a terminfo library, since the requisite information is not provided by the
       termcap emulation of terminfo libraries).

       Many of the special xterm features may be modified under program control through a set  of
       escape  sequences different from the standard VT102 escape sequences.  (See the Xterm Con-
       trol Sequences document.)

       The Tektronix 4014 emulation is also fairly good.  It supports 12-bit graphics addressing,
       scaled  to  the window size.  Four different font sizes and five different lines types are
       supported.  There is no write-through or defocused mode support.  The Tektronix	text  and
       graphics commands are recorded internally by xterm and may be written to a file by sending
       the COPY escape sequence (or through the Tektronix menu; see below).  The name of the file
       will  be  ``COPYyyyy-MM-dd.hh:mm:ss'',  where  yyyy,  MM,  dd, hh, mm and ss are the year,
       month, day, hour, minute and second when the COPY was performed (the file  is  created  in
       the directory xterm is started in, or the home directory for a login xterm).

       Not all of the features described in this manual are necessarily available in this version
       of xterm.  Some (e.g., the non-VT220 extensions) are available only if they were  compiled
       in, though the most commonly-used are in the default configuration.

OTHER FEATURES
       Xterm  automatically  highlights  the  text  cursor  when  the  pointer	enters the window
       (selected) and unhighlights it when the pointer leaves the window  (unselected).   If  the
       window  is  the	focus  window,	then  the  text cursor is highlighted no matter where the
       pointer is.

       In VT102 mode, there are escape sequences to activate and deactivate an	alternate  screen
       buffer,	which  is  the	same size as the display area of the window.  When activated, the
       current screen is saved and replaced with the alternate screen.	Saving of lines  scrolled
       off the top of the window is disabled until the normal screen is restored.  The termcap(5)
       entry for xterm allows the visual editor vi(1) to switch to the alternate screen for edit-
       ing  and  to  restore  the  screen  on exit.  A popup menu entry makes it simple to switch
       between the normal and alternate screens for cut and paste.

       In either VT102 or Tektronix mode, there are escape sequences to change the  name  of  the
       windows.   Additionally,  in  VT102 mode, xterm implements the window-manipulation control
       sequences from dtterm, such as resizing the window, setting its location on the screen.

       Xterm allows character-based applications to receive mouse events (currently  button-press
       and  release  events,  and button-motion events) as keyboard control sequences.	See Xterm
       Control Sequences for details.

OPTIONS
       The xterm terminal emulator accepts the standard X Toolkit command line options as well as
       many  application-specific options.  If the option begins with a `+' instead of a `-', the
       option is restored to its default value.  The -version and -help options  are  interpreted
       even  if  xterm	cannot	open  the  display,  and are useful for testing and configuration
       scripts:

       -version
	       This causes xterm to print a version number to the standard output.

       -help   This causes xterm to print out a verbose message describing its options,  one  per
	       line.   The  message is written to the standard output.	Xterm generates this mes-
	       sage, sorting it and noting whether a "-option" or a "+option" turns  the  feature
	       on  or  off,  since  some features historically have been one or the other.  Xterm
	       generates a concise help message (multiple  options  per  line)	when  an  unknown
	       option is used, e.g.,
		    xterm -z

	       If  the	logic for a particular option such as logging is not compiled into xterm,
	       the help text for that option also is not displayed by the -help option.

       One parameter (after all options) may be given.	That overrides xterm's built-in choice of
       shell program.  Normally xterm checks the SHELL variable.  If that is not set, xterm tries
       to use the shell program specified in the password file.  If that is not set,  xterm  uses
       /bin/sh.  If the parameter names an executable file, xterm uses that instead.  The parame-
       ter must be an absolute path, or name a file found on the user's PATH  (and  thereby  con-
       struct  an absolute path).  The -e option cannot be used with this parameter since it uses
       all parameters following the option.

       The other options are used to control the appearance and behavior.  Not	all  options  are
       necessarily configured into your copy of xterm:

       -132    Normally,  the VT102 DECCOLM escape sequence that switches between 80 and 132 col-
	       umn mode is ignored.  This option causes the DECCOLM escape sequence to be  recog-
	       nized, and the xterm window will resize appropriately.

       -ah     This  option  indicates	that  xterm  should always highlight the text cursor.  By
	       default, xterm will display a hollow text cursor whenever the focus is lost or the
	       pointer leaves the window.

       +ah     This  option  indicates	that  xterm  should  do text cursor highlighting based on
	       focus.

       -ai     This option disables active icon support if that feature was compiled into  xterm.
	       This is equivalent to setting the vt100 resource activeIcon to ``false''.

       +ai     This  option  enables active icon support if that feature was compiled into xterm.
	       This is equivalent to setting the vt100 resource activeIcon to ``true''.

       -aw     This option indicates that auto-wraparound should be  allowed.	This  allows  the
	       cursor  to  automatically wrap to the beginning of the next line when it is at the
	       rightmost position of a line and text is output.

       +aw     This option indicates that auto-wraparound should not be allowed.

       -b number
	       This option specifies the size of the inner border (the distance between the outer
	       edge of the characters and the window border) in pixels.  That is the vt100 inter-
	       nalBorder resource.  The default is 2.

       +bc     turn off text cursor blinking.  This overrides the cursorBlink resource.

       -bc     turn on text cursor blinking.  This overrides the cursorBlink resource.

       -bcf milliseconds
	       set the amount of time text cursor is off  when	blinking  via  the  cursorOffTime
	       resource.

       -bcn milliseconds
	       set  the  amount  of  time  text  cursor is on when blinking via the cursorOffTime
	       resource.

       -bdc    Set the vt100 resource colorBDMode to ``false'', disabling the display of  charac-
	       ters with bold attribute as color

       +bdc    Set the vt100 resource colorBDMode to ``true'', enabling the display of characters
	       with bold attribute as color rather than bold

       -cb     Set the vt100 resource cutToBeginningOfLine to ``false''.

       +cb     Set the vt100 resource cutToBeginningOfLine to ``true''.

       -cc characterclassrange:value[,...]
	       This sets classes indicated by the given ranges for using in selecting  by  words.
	       See  the  section  specifying  character classes.  and discussion of the charClass
	       resource.

       -cjk_width
	       Set the cjkWidth resource to ``true''.  When turned on, characters with East Asian
	       Ambiguous (A) category in UTR 11 have a column width of 2.  Otherwise, they have a
	       column width of 1.  This may be useful for some	legacy	CJK  text  terminal-based
	       programs  assuming  box	drawings and others to have a column width of 2.  It also
	       should  be  turned  on  when  you  specify  a  TrueType	CJK   double-width   (bi-
	       width/monospace)  font  either  with -fa at the command line or faceName resource.
	       The default is ``false''

       +cjk_width
	       Reset the cjkWidth resource.

       -class string
	       This option allows you  to  override  xterm's  resource	class.	 Normally  it  is
	       ``XTerm'', but can be set to another class such as ``UXTerm'' to override selected
	       resources.

       -cm     This option disables recognition of ANSI color-change escape sequences.	 It  sets
	       the colorMode resource to ``false''.

       +cm     This  option  enables  recognition of ANSI color-change escape sequences.  This is
	       the same as the vt100 resource colorMode.

       -cn     This option indicates that newlines should not be cut in line-mode selections.  It
	       sets the cutNewline resource to ``false''.

       +cn     This  option  indicates	that  newlines should be cut in line-mode selections.  It
	       sets the cutNewline resource to ``true''.

       -cr color
	       This option specifies the color to use for text cursor.	The default is to use the
	       same  foreground  color	that  is used for text.  It sets the cursorColor resource
	       according to the parameter.

       -cu     This option indicates that xterm should work around a bug in the  more(1)  program
	       that causes it to incorrectly display lines that are exactly the width of the win-
	       dow and are followed by a line beginning with a tab (the leading tabs are not dis-
	       played).  This option is so named because it was originally thought to be a bug in
	       the curses(3x) cursor motion package.

       +cu     This option indicates that xterm should not work around the more(1) bug	mentioned
	       above.

       -dc     This option disables the escape sequence to change dynamic colors: the vt100 fore-
	       ground and background colors, its text cursor color, the pointer cursor foreground
	       and  background	colors,  the Tektronix emulator foreground and background colors,
	       its text cursor color and highlight color.   The  option  sets  the  dynamicColors
	       option to ``false''.

       +dc     This option enables the escape sequence to change dynamic colors.  The option sets
	       the dynamicColors option to ``true''.

       -e program [ arguments ... ]
	       This option specifies the program (and its command line arguments) to  be  run  in
	       the  xterm window.  It also sets the window title and icon name to be the basename
	       of the program being executed if neither -T nor -n are given on the command  line.
	       This must be the last option on the command line.

       -en encoding
	       This  option  determines  the  encoding	on  which xterm runs.  It sets the locale
	       resource.  Encodings other than UTF-8 are supported by using luit.  The -lc option
	       should be used instead of -en for systems with locale support.

       -fb font
	       This option specifies a font to be used when displaying bold text.  This font must
	       be the same height and width as the normal font.  If only one  of  the  normal  or
	       bold fonts is specified, it will be used as the normal font and the bold font will
	       be produced by overstriking this font.  The default is to do overstriking  of  the
	       normal  font.   See  also  the discussion of boldFont, boldMode and alwaysBoldMode
	       resources.

       -fa pattern
	       This option sets the pattern for fonts selected from the FreeType library if  sup-
	       port  for  that library was compiled into xterm.  This corresponds to the faceName
	       resource.  When a CJK double-width font is specified, you also need to turn on the
	       cjkWidth  resource.  See also the renderFont resource, which combines with this to
	       determine whether FreeType fonts are initially active.

       -fbb    This option indicates that xterm should compare normal  and  bold  fonts  bounding
	       boxes  to  ensure  they	are  compatible.   It  sets  the  freeBoldBox resource to
	       ``false''.

       +fbb    This option indicates that xterm should not compare normal and bold fonts bounding
	       boxes  to  ensure  they	are  compatible.   It  sets  the  freeBoldBox resource to
	       ``true''.

       -fbx    This option indicates that xterm should not assume that the normal and bold  fonts
	       have VT100 line-drawing characters.  If any are missing, xterm will draw the char-
	       acters directly.  It sets the forceBoxChars resource to ``false''.

       +fbx    This option indicates that xterm should assume that the normal and bold fonts have
	       VT100 line-drawing characters.  It sets the forceBoxChars resource to ``true''.

       -fd pattern
	       This  option  sets  the	pattern for double-width fonts selected from the FreeType
	       library if support for that library was compiled into xterm.  This corresponds  to
	       the faceNameDoublesize resource.

       -fi font
	       This  option  sets  the	font  for  active icons if that feature was compiled into
	       xterm.  See also the discussion of the iconFont resource.

       -fs size
	       This option sets the pointsize for fonts selected from  the  FreeType  library  if
	       support	for  that library was compiled into xterm.  This corresponds to the face-
	       Size resource.

       -fw font
	       This option specifies the font to be used for displaying wide text.   By  default,
	       it  will attempt to use a font twice as wide as the font that will be used to draw
	       normal text.  If no doublewidth font is found, it will  improvise,  by  stretching
	       the normal font.  This corresponds to the wideFont resource.

       -fwb font
	       This  option  specifies	the  font  to  be used for displaying bold wide text.  By
	       default, it will attempt to use a font twice as wide as the font that will be used
	       to  draw  bold  text.   If  no  doublewidth  font  is found, it will improvise, by
	       stretching the bold font.  This corresponds to the wideBoldFont resource.

       -fx font
	       This option specifies the font to be used for displaying the preedit string in the
	       "OverTheSpot" input method.  See also the discussion of the ximFont resource.

       -hc color
	       (see -selbg).

       -hf     This  option  indicates	that HP Function Key escape codes should be generated for
	       function keys.  It sets the hpFunctionKeys resource to ``true''.

       +hf     This option indicates that HP Function Key escape codes should  not  be	generated
	       for function keys.  It sets the hpFunctionKeys resource to ``false''.

       -hm     Tells  xterm to use highlightTextColor and highlightColor to override the reversed
	       foreground/background colors in	a  selection.	It  sets  the  highlightColorMode
	       resource to ``true''.

       +hm     Tells  xterm  not  to  use  highlightTextColor  and highlightColor to override the
	       reversed foreground/background colors in a selection.  It sets the highlightColor-
	       Mode resource to ``false''.

       -hold   Turn  on  the  hold  resource, i.e., xterm will not immediately destroy its window
	       when the shell command completes.  It will wait until you use the  window  manager
	       to  destroy/kill  the  window,  or if you use the menu entries that send a signal,
	       e.g., HUP or KILL.

       +hold   Turn off the hold resource, i.e., xterm will immediately destroy its  window  when
	       the shell command completes.

       -ie     Turn on the ptyInitialErase resource, i.e., use the pseudo-terminal's sense of the
	       stty erase value.

       +ie     Turn off the ptyInitialErase resource, i.e., set the stty erase value using the kb
	       string from the termcap entry as a reference, if available.

       -im     Turn  on  the  useInsertMode  resource,	which forces use of insert mode by adding
	       appropriate entries to the TERMCAP environment variable.

       +im     Turn off the useInsertMode resource.

       -into windowId
	       Given an X window identifier (a decimal integer), xterm	will  reparent	its  top-
	       level  shell  widget  to  that  window.	 This is used to embed xterm within other
	       applications.

       -j      This option indicates that xterm should do jump scrolling.  It corresponds to  the
	       jumpScroll  resource.   Normally, text is scrolled one line at a time; this option
	       allows xterm to move multiple lines at a time so that it  does  not  fall  as  far
	       behind.	 Its  use  is  strongly recommended since it makes xterm much faster when
	       scanning through large amounts of text.	The VT100 escape sequences  for  enabling
	       and disabling smooth scroll as well as the ``VT Options'' menu can be used to turn
	       this feature on or off.

       +j      This option indicates that xterm should not do jump scrolling.

       -k8     This option sets the allowC1Printable resource.	 When  allowC1Printable  is  set,
	       xterm  overrides the mapping of C1 control characters (code 128-159) to treat them
	       as printable.

       +k8     This option resets the allowC1Printable resource.

       -kt keyboardtype
	       This option sets the keyboardType resource.  Possible values include: ``unknown'',
	       ``default'', ``hp'', ``sco'', ``sun'', ``tcap'' and ``vt220''.

	       The value ``unknown'', causes the corresponding resource to be ignored.

	       The  value  ``default'',  suppresses the associated resources hpFunctionKeys, sco-
	       FunctionKeys, sunFunctionKeys, tcapFunctionKeys and sunKeyboard, using the  Sun/PC
	       keyboard layout.

       -l      Turn  logging  on.   Normally  logging is not supported, due to security concerns.
	       Some versions of xterm may have logging enabled.  The logfile is  written  to  the
	       directory from which xterm is invoked.  The filename is generated, of the form

		    XtermLog.XXXXXX

	       or

		    Xterm.log.hostname.yyyy.mm.dd.hh.mm.ss.XXXXXX

	       depending on how xterm was built.

       +l      Turn logging off.

       -lc     Turn on support of various encodings according to the users' locale setting, i.e.,
	       LC_ALL, LC_CTYPE, or LANG environment variables.  This is achieved by  turning  on
	       UTF-8 mode and by invoking luit for conversion between locale encodings and UTF-8.
	       (luit is not invoked in UTF-8 locales.)	This corresponds to the locale resource.

	       The actual list of encodings which are supported is determined by  luit.   Consult
	       the  luit  manual  page	for  further details.  See also the discussion of the -u8
	       option which supports UTF-8 locales.

       +lc     Turn off support of automatic selection of locale  encodings.   Conventional  8bit
	       mode or, in UTF-8 locales or with -u8 option, UTF-8 mode will be used.

       -lcc path
	       File  name  for the encoding converter from/to locale encodings and UTF-8 which is
	       used with -lc option or locale resource.  This  corresponds  to	the  localeFilter
	       resource.

       -leftbar
	       Force scrollbar to the left side of VT100 screen.  This is the default, unless you
	       have set the rightScrollBar resource.

       -lf filename
	       Specify the log-filename.  See the -l option.

       -ls     This option indicates that the shell that is started in the xterm window will be a
	       login  shell  (i.e.,  the first character of argv[0] will be a dash, indicating to
	       the shell that it should read the user's .login or .profile).

	       The -ls flag and the loginShell resource are ignored if -e is also given,  because
	       xterm  does  not know how to make the shell start the given command after whatever
	       it does when it is a login shell - the user's shell of choice need not be a Bourne
	       shell after all.  Also, xterm -e is supposed to provide a consistent functionality
	       for other applications that need to start text-mode programs in a window,  and  if
	       loginShell were not ignored, the result of ~/.profile might interfere with that.

	       If  you	do  want  the  effect of -ls and -e simultaneously, you may get away with
	       something like
		      xterm -e /bin/bash -l -c "my command here"

	       Finally, -ls  is  not  completely  ignored,  because  xterm -ls -e  does  write	a
	       /etc/wtmp entry (if configured to do so), whereas xterm -e does not.

       -maximized
	       This  option  indicates	that  xterm should ask the window manager to maximize its
	       layout on startup.  This corresponds to the maximized resource.

	       Maximizing is not the reverse of iconifying; it is possible to do both  with  cer-
	       tain window managers.

       +maximized
	       This  option  indicates	that  xterm should ask the window manager to maximize its
	       layout on startup.

       +ls     This option indicates that the shell that is started should not be a  login  shell
	       (i.e., it will be a normal ``subshell'').

       -mb     This  option  indicates	that  xterm should ring a margin bell when the user types
	       near the right end of a line.  This option can be turned on and off from the  ``VT
	       Options'' menu.

       +mb     This option indicates that margin bell should not be rung.

       -mc milliseconds
	       This option specifies the maximum time between multi-click selections.

       -mesg   Turn off the messages resource, i.e., disallow write access to the terminal.

       +mesg   Turn on the messages resource, i.e., allow write access to the terminal.

       -mk_width
	       Set  the mkWidth resource to ``true''.  This makes xterm use a built-in version of
	       the wide-character width calculation.  The default is ``false''

       +mk_width
	       Reset the mkWidth resource.

       -ms color
	       This option specifies the color to be used for the pointer cursor.  The default is
	       to use the foreground color.  This sets the pointerColor resource.

       -nb number
	       This  option  specifies	the  number of characters from the right end of a line at
	       which the margin bell, if enabled, will ring.  The default is 10.

       -nul    This option disables the display of underlining.

       +nul    This option enables the display of underlining.

       -pc     This option enables the PC-style use of bold colors (see boldColors resource).

       +pc     This option disables the PC-style use of bold colors.

       -pob    This option indicates that the window should be raised  whenever  a  Control-G  is
	       received.

       +pob    This option indicates that the window should not be raised whenever a Control-G is
	       received.

       -rightbar
	       Force scrollbar to the right side of VT100 screen.

       -rvc    This option disables the display of characters with reverse attribute as color.

       +rvc    This option enables the display of characters with reverse attribute as color.

       -rw     This option indicates that reverse-wraparound should be allowed.  This allows  the
	       cursor  to back up from the leftmost column of one line to the rightmost column of
	       the previous line.  This is very useful for editing long shell command  lines  and
	       is encouraged.  This option can be turned on and off from the ``VT Options'' menu.

       +rw     This option indicates that reverse-wraparound should not be allowed.

       -s      This  option  indicates	that  xterm  may  scroll asynchronously, meaning that the
	       screen does not have to be kept completely  up  to  date  while	scrolling.   This
	       allows  xterm  to run faster when network latencies are very high and is typically
	       useful when running across a very large internet or many gateways.

       +s      This option indicates that xterm should scroll synchronously.

       -samename
	       Does not send title and icon name change requests when the request would  have  no
	       effect: the name is not changed.  This has the advantage of preventing flicker and
	       the disadvantage of requiring an extra round trip to the server to  find  out  the
	       previous value.	In practice this should never be a problem.

       +samename
	       Always send title and icon name change requests.

       -sb     This  option  indicates that some number of lines that are scrolled off the top of
	       the window should be saved and that a scrollbar should be displayed so that  those
	       lines can be viewed.  This option may be turned on and off from the ``VT Options''
	       menu.

       +sb     This option indicates that a scrollbar should not be displayed.

       -selbg color
	       This option specifies the color to use for the background of  selected  text.   If
	       not  specified,	reverse  video is used.  See the discussion of the highlightColor
	       resource.

       -selfg color
	       This option specifies the color to use  for  selected  text.   If  not  specified,
	       reverse video is used.  See the discussion of the highlightTextColor resource.

       -sf     This  option  indicates that Sun Function Key escape codes should be generated for
	       function keys.

       +sf     This option indicates that the standard escape codes should be generated for func-
	       tion keys.

       -si     This  option indicates that output to a window should not automatically reposition
	       the screen to the bottom of the scrolling region.  This option can  be  turned  on
	       and off from the ``VT Options'' menu.

       +si     This  option  indicates	that  output to a window should cause it to scroll to the
	       bottom.

       -sk     This option indicates that pressing a key while using the scrollbar to review pre-
	       vious  lines  of  text should cause the window to be repositioned automatically in
	       the normal position at the bottom of the scroll region.

       +sk     This option indicates that pressing a key while using  the  scrollbar  should  not
	       cause the window to be repositioned.

       -sl number
	       This  option specifies the number of lines to save that have been scrolled off the
	       top of the screen.  This corresponds to the saveLines resource.	 The  default  is
	       64.

       -sm     This option, corresponding to the sessionMgt resource, indicates that xterm should
	       set up session manager callbacks.

       +sm     This option indicates that xterm should not set up session manager callbacks.

       -sp     This option indicates that Sun/PC keyboard should be  assumed,  providing  mapping
	       for keypad `+' to `,', and CTRL-F1 to F13, CTRL-F2 to F14, etc.

       +sp     This  option indicates that the standard escape codes should be generated for key-
	       pad and function keys.

       -t      This option indicates that xterm should start in Tektronix mode,  rather  than  in
	       VT102  mode.   Switching  between  the  two  windows is done using the ``Options''
	       menus.	Termcap(5)  entries  that  work  with  xterm  ``tek4014,''   ``tek4015,''
	       ``tek4012'',  ``tek4013''  and  ``tek4010,''  and  ``dumb.''   xterm automatically
	       searches the termcap file in this order	for  these  entries  and  then	sets  the
	       ``TERM'' and the ``TERMCAP'' environment variables.

       +t      This option indicates that xterm should start in VT102 mode.

       -tb     This  option,  corresponding  to the toolBar resource, indicates that xterm should
	       display a toolbar (or menubar) at the top of its window.  The buttons in the tool-
	       bar correspond to the popup menus, e.g., control/left/mouse for "Main Options".

       +tb     This option indicates that xterm should not set up a toolbar.

       -ti term_id
	       Specify	the  name  used  by  xterm  to select the correct response to terminal ID
	       queries.  It also specifies the emulation level, used to  determine  the  type  of
	       response  to  a	DA  control  sequence.	 Valid values include vt52, vt100, vt101,
	       vt102, and vt220 (the "vt" is optional).  The default is vt100.	The term_id argu-
	       ment  specifies	the  terminal  ID to use.  (This is the same as the decTerminalID
	       resource).

       -tm string
	       This option specifies a series of terminal setting keywords followed by the  char-
	       acters  that should be bound to those functions, similar to the stty program.  The
	       keywords and their values are described in detail in the ttyModes resource.

       -tn name
	       This option specifies the name of the terminal type to be set in the TERM environ-
	       ment  variable.	It corresponds to the termName resource.  This terminal type must
	       exist in the terminal database (termcap or terminfo, depending  on  how	xterm  is
	       built)  and  should  have li# and co# entries.  If the terminal type is not found,
	       xterm uses the built-in list ``xterm'', ``vt102'', etc.

       -u8     This option sets the utf8 resource.  When utf8 is set, xterm  interprets  incoming
	       data  as  UTF-8.  This sets the wideChars resource as a side-effect, but the UTF-8
	       mode set by this option prevents it from being turned off.  If you must turn it on
	       and off, use the wideChars resource.

	       This  option  and  the utf8 resource are overridden by the -lc and -en options and
	       locale resource.  That is, if xterm has been compiled to  support  luit,  and  the
	       locale  resource  is not ``false'' this option is ignored.  We recommend using the
	       -lc option or the ``locale: true'' resource in UTF-8 locales when  your	operating
	       system supports locale, or -en UTF-8 option or the ``locale: UTF-8'' resource when
	       your operating system does not support locale.

       +u8     This option resets the utf8 resource.

       -uc     This option makes the cursor underlined instead of a box.

       +uc     This option makes the cursor a box instead of underlined.

       -ulc    This option disables the display of characters with underline attribute	as  color
	       rather than with underlining.

       +ulc    This  option  enables  the display of characters with underline attribute as color
	       rather than with underlining.

       -ulit   This option, corresponding to the italicULMode resource, disables the  display  of
	       characters with underline attribute as italics rather than with underlining.

       +ulit   This  option,  corresponding  to the italicULMode resource, enables the display of
	       characters with underline attribute as italics rather than with underlining.

       -ut     This option indicates that xterm should not write a record  into  the  the  system
	       utmp log file.

       +ut     This  option  indicates	that xterm should write a record into the system utmp log
	       file.

       -vb     This option indicates that a  visual  bell  is  preferred  over	an  audible  one.
	       Instead	of ringing the terminal bell whenever a Control-G is received, the window
	       will be flashed.

       +vb     This option indicates that a visual bell should not be used.

       -wc     This option sets the wideChars resource.  When wideChars is set,  xterm	maintains
	       internal  structures  for  16-bit  characters.  If you do not set this resource to
	       ``true'', xterm will ignore the escape sequence which turns UTF-8 mode on and off.
	       The default is ``false''.

       +wc     This option resets the wideChars resource.

       -wf     This option indicates that xterm should wait for the window to be mapped the first
	       time before starting the subprocess so that the initial terminal size settings and
	       environment  variables  are  correct.   It  is the application's responsibility to
	       catch subsequent terminal size changes.

       +wf     This option indicates that xterm should not wait before starting the subprocess.

       -ziconbeep percent
	       Same as zIconBeep resource.  If percent is non-zero, xterms  that  produce  output
	       while  iconified  will  cause  an  XBell  sound at the given volume and have "***"
	       prepended to their icon titles.	Most window  managers  will  detect  this  change
	       immediately,  showing  you which window has the output.	(A similar feature was in
	       x10 xterm.)

       -C      This option indicates that this window should receive console output.  This is not
	       supported  on all systems.  To obtain console output, you must be the owner of the
	       console device, and you must have read and write permission for it.   If  you  are
	       running X under xdm on the console screen you may need to have the session startup
	       and reset programs explicitly change the ownership of the console device in  order
	       to get this option to work.

       -Sccn   This option allows xterm to be used as an input and output channel for an existing
	       program and is sometimes used in specialized applications.  The option value spec-
	       ifies  the last few letters of the name of a pseudo-terminal to use in slave mode,
	       plus the number of the inherited file descriptor.  If the option contains a  ``/''
	       character, that delimits the characters used for the pseudo-terminal name from the
	       file descriptor.  Otherwise, exactly two characters are used from the  option  for
	       the pseudo-terminal name, the remainder is the file descriptor.	Examples:
		      -S123/45
		      -Sab34

	       Note  that  xterm does not close any file descriptor which it did not open for its
	       own use.  It is possible (though probably not portable)	to  have  an  application
	       which  passes an open file descriptor down to xterm past the initialization or the
	       -S option to a process running in the xterm.

       The following command line arguments are provided for compatibility with  older	versions.
       They  may  not be supported in the next release as the X Toolkit provides standard options
       that accomplish the same task.

       %geom   This option specifies the preferred size and position of the Tektronix window.  It
	       is shorthand for specifying the ``*tekGeometry'' resource.

	#geom  This  option specifies the preferred position of the icon window.  It is shorthand
	       for specifying the ``*iconGeometry'' resource.

       -T string
	       This option specifies the title for xterm's windows.  It is equivalent to -title.

       -n string
	       This option specifies the icon name for xterm's	windows.   It  is  shorthand  for
	       specifying  the	``*iconName''  resource.   Note  that this is not the same as the
	       toolkit option -name (see below).  The default icon name is the application name.

       -r      This option indicates that reverse video should be simulated by swapping the fore-
	       ground and background colors.  It is equivalent to -rv.

       -w number
	       This  option  specifies	the width in pixels of the border surrounding the window.
	       It is equivalent to -borderwidth or -bw.

       The following standard X Toolkit command line arguments are commonly used with xterm:

       -bd color
	       This option specifies the color to use for the border of the window.   xterm  uses
	       the X Toolkit default, which is ``XtDefaultForeground''.

       -bg color
	       This  option  specifies	the  color  to use for the background of the window.  The
	       default is ``XtDefaultBackground.''

       -bw number
	       This option specifies the width in pixels of the border surrounding the window.

	       This appears to be a legacy of older X releases.  It sets the borderWidth resource
	       of  the	shell  widget,	and  may provide advice to your window manager to set the
	       thickness of the window frame.  Most window managers do not use this  information.
	       See the -b option, which controls the inner border of the xterm window.

       -display display
	       This option specifies the X server to contact; see X().

       -fg color
	       This  option  specifies	the  color  to	use  for displaying text.  The default is
	       ``XtDefaultForeground.''

       -fn font
	       This option specifies the font to be used for displaying normal text.  The default
	       is fixed.

       -font font
	       This is the same as -fn.

       -geometry geometry
	       This  option  specifies	the  preferred size and position of the VT102 window; see
	       X().

       -iconic This option indicates that xterm should ask the window manager to start it  as  an
	       icon rather than as the normal window.

       -name name
	       This  option  specifies	the  application  name	under  which  resources are to be
	       obtained, rather than the default executable file name.	Name should  not  contain
	       ``.'' or ``*'' characters.

       -rv     This option indicates that reverse video should be simulated by swapping the fore-
	       ground and background colors.

       +rv     Disable the simulation of reverse video by swapping foreground and background col-
	       ors.

       -title string
	       This  option  specifies	the window title string, which may be displayed by window
	       managers if the user so chooses.  The default title is the command line	specified
	       after the -e option, if any, otherwise the application name.

       -xrm resourcestring
	       This option specifies a resource string to be used.  This is especially useful for
	       setting resources that do not have separate command line options.

RESOURCES
       The program understands all of the core X Toolkit resource names and classes.  Application
       specific resources (e.g., "XTerm.NAME") follow:

       backarrowKeyIsErase (class BackarrowKeyIsErase)
	       Tie  the  VTxxx backarrowKey and ptyInitialErase resources together by setting the
	       DECBKM state according to whether the initial value of stty erase is  a	backspace(8) or delete(127) character.  The default is ``false'', which disables this fea-
	       ture.

       hold (class Hold)
	       If true, xterm will not immediately destroy its window when the shell command com-
	       pletes.	It will wait until you use the window manager to destroy/kill the window,
	       or if you use the menu entries that send a signal, e.g., HUP  or  KILL.	 You  may
	       scroll  back,  select  text, etc., to perform most graphical operations.  Resizing
	       the display will lose data, however, since  this  involves  interaction	with  the
	       shell which is no longer running.

       hpFunctionKeys (class HpFunctionKeys)
	       Specifies  whether  or  not  HP	Function Key escape codes should be generated for
	       function keys instead of standard escape sequences.   See  also	the  keyboardType
	       resource.

       iconGeometry (class IconGeometry)
	       Specifies  the  preferred size and position of the application when iconified.  It
	       is not necessarily obeyed by all window managers.

       iconName (class IconName)
	       Specifies the icon name.  The default is the application name.

       keyboardType (class KeyboardType)
	       Enables one (or none) of the various keyboard-type resources: hpFunctionKeys, sco-
	       FunctionKeys,  sunFunctionKeys,	tcapFunctionKeys and sunKeyboard.  The resource's
	       value should be	one  of  the  corresponding  strings  ``hp'',  ``sco'',  ``sun'',
	       ``tcap''  or ``vt220''.	The individual resources are provided for legacy support;
	       this resource is simpler to use.

       maxBufSize (class MaxBufSize)
	       Specify the maximum size of the input buffer.  The default is 32768.   You  cannot
	       set  this  to  a value less than the minBufSize resource.  It will be increased as
	       needed to make that value evenly divide this one.

	       On some systems you may want to increase one or both of the maxBufSize and minBuf-
	       Size resource values to achieve better performance if the operating system prefers
	       larger buffer sizes.

       maximized (class Maximized)
	       Specifies whether or not xterm should ask the window manager to maximize its  lay-
	       out on startup.	The default is ``false.''

       messages (class Messages)
	       Specifies whether write access to the terminal is allowed initially.  See mesg(1).
	       The default is ``true''.

       menuLocale (class MenuLocale)
		Specify the locale used for character-set computations	when  loading  the  popup
		menus.	Use this to improve initialization performance of the Athena popup menus,
		which may load unnecessary (and very large) fonts, e.g., in a locale having UTF-8
		encoding.  The default is an empty string, which uses the current locale setting.

		Set  it  to ``C'' to achieve the best performance using the default menu resource
		settings.  If you happen to be using localized menu resources, set  the  resource
		accordingly.

       minBufSize (class MinBufSize)
	       Specify	the minimum size of the input buffer, i.e., the amount of data that xterm
	       requests on each read.  The default is 4096.  You cannot set this to a value  less
	       than 64.

       ptyHandshake (class PtyHandshake)
	       If  ``true'',  xterm will perform handshaking during initialization to ensure that
	       the parent and child processes update the utmp and stty	state.	 See  also  wait-
	       ForMap which waits for the pseudo-terminal's notion of the screen size, and ptySt-
	       tySize which resets the screen size after other terminal  initialization  is  com-
	       plete.  The default is ``true''.

       ptyInitialErase (class PtyInitialErase)
	       If  ``true'',  xterm will use the pseudo-terminal's sense of the stty erase value.
	       If ``false'', xterm will set the stty erase value to match its own  configuration,
	       using  the  kb  string  from  the  termcap entry as a reference, if available.  In
	       either case, the result is applied to the TERMCAP variable which xterm sets.   See
	       also the ttyModes resource, which may modify this.  The default is ``false''.

       ptySttySize (class PtySttySize)
	       If  ``true'',  xterm  will  reset the screen size after terminal initialization is
	       complete.  This is needed for some systems whose pseudo-terminals cannot propagate
	       terminal  characteristics.   Where  it  is not needed, it can interfere with other
	       methods for setting the intial screen size, e.g., via window manager  interaction.
	       See  also  waitForMap which waits for a handshake-message giving the pseudo-termi-
	       nal's notion of the screen size.  The default is ``false'' on Linux and OS X  sys-
	       tems, ``true'' otherwise.

       sameName (class SameName)
	       If the value of this resource is ``true'', xterm does not send title and icon name
	       change requests when the request would have no effect: the name	is  not  changed.
	       This  has the advantage of preventing flicker and the disadvantage of requiring an
	       extra round trip to the server to find out the previous value.  In  practice  this
	       should never be a problem.  The default is ``true''.

       scoFunctionKeys (class ScoFunctionKeys)
	       Specifies  whether  or  not  SCP Function Key escape codes should be generated for
	       function keys instead of standard escape sequences.   See  also	the  keyboardType
	       resource.

       sessionMgt (class SessionMgt)
	       If the value of this resource is ``true'', xterm sets up session manager callbacks
	       for XtNdieCallback and XtNsaveCallback.	The default is ``true''.

       sunFunctionKeys (class SunFunctionKeys)
	       Specifies whether or not Sun Function Key escape codes  should  be  generated  for
	       function  keys  instead	of  standard escape sequences.	See also the keyboardType
	       resource.

       sunKeyboard (class SunKeyboard)
	       Specifies whether or not Sun/PC keyboard layout should be assumed rather than  DEC
	       VT220.	This  causes  the  keypad  `+'	to  be mapped to `,'.  and CTRL F1-F12 to
	       F11-F20, depending on the setting of the ctrlFKeys resource.  so xterm emulates	a
	       DEC  VT220  more  accurately.   Otherwise  (the	default,  with sunKeyboard set to
	       ``false''), xterm uses PC-style bindings for the function keys and keypad.

	       PC-style bindings use the Shift, Alt, Control and Meta keys as modifiers for func-
	       tion-keys  and keypad (see the document Xterm Control Sequences for details).  The
	       PC-style bindings are analogous to PCTerm, but not the same thing.  Normally these
	       bindings  do not conflict with the use of the Meta key as described for the eight-
	       BitInput resource.  If they do, note that  the  PC-style  bindings  are	evaluated
	       first.  See also the keyboardType resource.

       tcapFunctionKeys (class TcapFunctionKeys)
	       Specifies  whether or not function key escape codes read from the termcap/terminfo
	       entry should be generated for function keys instead of standard escape  sequences.
	       See also the keyboardType resource.

       termName (class TermName)
	       Specifies the terminal type name to be set in the TERM environment variable.

       title (class Title)
	       Specifies  a  string  that  may be used by the window manager when displaying this
	       application.

       toolBar (class ToolBar)
	       Specifies whether or  not  the  toolbar	should	be  displayed.	 The  default  is
	       ``true.''

       ttyModes (class TtyModes)
	       Specifies  a  string  containing  terminal  setting keywords and the characters to
	       which they may be bound.  Allowable keywords include: brk, dsusp, eof, eol,  eol2,
	       erase,  erase2,	flush, intr, kill, lnext, quit, rprnt, start, status, stop, susp,
	       swtch and weras.  Control characters may be specified as ^char (e.g.,  ^c  or  ^u)
	       and ^? may be used to indicate delete(127).  Use ^- to denote undef.  Use \034 to
	       represent ^\, since a literal backslash in an X resource escapes the next  charac-
	       ter.

	       This is very useful for overriding the default terminal settings without having to
	       do an stty every time an xterm is started.  Note, however, that the  stty  program
	       on a given host may use different keywords; xterm's table is built-in.

	       If  the	ttyModes resource specifies a value for erase, that overrides the ptyIni-
	       tialErase resource setting, i.e., xterm initializes the	terminal  to  match  that
	       value.

       useInsertMode (class UseInsertMode)
	       Force  use of insert mode by adding appropriate entries to the TERMCAP environment
	       variable.  This is useful if  the  system  termcap  is  broken.	 The  default  is
	       ``false.''

       utmpDisplayId (class UtmpDisplayId)
	       Specifies  whether  or not xterm should try to record the display identifier (dis-
	       play number and screen number) as well as the hostname  in  the	system	utmp  log
	       file.  The default is ``true.''

       utmpInhibit (class UtmpInhibit)
	       Specifies  whether  or  not  xterm should try to record the user's terminal in the
	       system utmp log file.  If true, xterm will not try.  The default is ``false.''

       waitForMap (class WaitForMap)
	       Specifies whether or not xterm should wait  for	the  initial  window  map  before
	       starting  the  subprocess.  This is part of the ptyHandshake logic.  When xterm is
	       directed to wait in this fashion, it passes the terminal size from the display end
	       of the pseudo-terminal to the terminal I/O connection, e.g., according to the win-
	       dow manager.  Otherwise, it uses the size as given in resource values or  command-
	       line option -geom.  The default is ``false.''

       zIconBeep (class ZIconBeep)
	       Same  as  -ziconbeep command line argument.  If the value of this resource is non-
	       zero, xterms that produce output while iconified will cause an XBell sound at  the
	       given  volume and have "***" prepended to their icon titles.  Most window managers
	       will detect this change immediately, showing you which window has the output.   (A
	       similar feature was in x10 xterm.)  The default is ``false.''

   VT100 Widget Resources
       The following resources are specified as part of the vt100 widget (class VT100).  They are
       specified by patterns such as "XTerm.vt100.NAME".

       If your xterm is configured to support the "toolbar", then those patterns  need	an  extra
       level  for  the	form-widget which holds the toolbar and vt100 widget.  A wildcard between
       the top-level "XTerm" and the "vt100" widget makes the resource settings work for  either,
       e.g., "XTerm*vt100.NAME".

       activeIcon (class ActiveIcon)
	       Specifies  whether or not active icon windows are to be used when the xterm window
	       is iconified, if this feature is compiled into xterm.  The active icon is a minia-
	       ture  representation  of  the content of the window and will update as the content
	       changes.  Not all window managers necessarily support  application  icon  windows.
	       Some  window managers will allow you to enter keystrokes into the active icon win-
	       dow.  The default is ``false.''

       allowC1Printable (class AllowC1Printable)
	       If true, overrides the mapping of C1 controls (codes  128-159)  to  make  them  be
	       treated	as  if	they  were printable characters.  Although this corresponds to no
	       particular standard, some users insist it is a VT100.  The default is ``false.''

       allowFontOps (class AllowFontOps)
	       Specifies whether control sequences that set/query the  font  should  be  allowed.
	       The default is ``true.''

       allowSendEvents (class AllowSendEvents)
	       Specifies  whether  or  not synthetic key and button events (generated using the X
	       protocol SendEvent request) should be interpreted or discarded.	 The  default  is
	       ``false''  meaning  they  are discarded.  Note that allowing such events creates a
	       very large security hole.  The default is ``false.''

       allowTcapOps (class AllowTcapOps)
	       Specifies whether control sequences that query the terminal's notion of its  func-
	       tion-key  strings,  as  termcap	or  terminfo capabilities should be allowed.  The
	       default is ``false.''

	       A few programs, e.g,. vim, use this feature to get an accurate description of  the
	       terminal's capabilities, independent of the termcap/terminfo setting:

	       -  xterm  can  tell  the  querying program how many colors it supports.	This is a
		  constant, depending on how it is compiled, typically 16.  It does not change if
		  you alter resource settings, e.g., the boldColors resource.

	       -  xterm  can tell the querying program what strings are sent by modified (shift-,
		  control-, alt-) function- and keypad-keys.  Reporting  control-  and	alt-modi-
		  fiers is a feature that relies on the ncurses extended naming.

       allowTitleOps (class AllowTitleOps)
	       Specifies  whether  control  sequences  that  modify the window title or icon name
	       should be allowed.  The default is ``true.''

       allowWindowOps (class AllowWindowOps)
	       Specifies whether extended window control sequences (as used in dtterm) should  be
	       allowed.  The default is ``true.''

       altIsNotMeta (class AltIsNotMeta)
	       If ``true'', treat the Alt-key as if it were the Meta-key.  Your keyboard may hap-
	       pen to be configured so they are the same.  But if they are not, this  allows  you
	       to use the same prefix- and shifting operations with the Alt-key as with the Meta-
	       key.  See altSendsEscape and metaSendsEscape.  The default is ``false.''

       altSendsEscape (class AltSendsEscape)
	       This is an additional keyboard operation that may be processed after the logic for
	       metaSendsEscape.  It is only available if the altIsNotMeta resource is set.

	       If  ``true'',  Alt  characters  (a character combined with the modifier associated
	       with left/right Alt-keys) are converted into a  two-character  sequence	with  the
	       character  itself  preceded  by ESC.  This applies as well to function key control
	       sequences, unless xterm sees that Alt  is  used	in  your  key  translations.   If
	       ``false'',  Alt	characters input from the keyboard cause a shift to 8-bit charac-
	       ters (just like metaSendsEscape).  By combining the Alt- and  Meta-modifiers,  you
	       can  create  corresponding  combinations  of ESC-prefix and 8-bit characters.  The
	       default is ``false.''

       alwaysBoldMode (class AlwaysBoldMode)
	       Specifies whether xterm should check if the normal and  bold  fonts  are  distinct
	       before  deciding  whether  to  use  overstriking  to simulate bold fonts.  If this
	       resource is true, xterm does not make the check for distinct fonts  when  deciding
	       how to handle the boldMode resource.  The default is ``false.''

	       boldMode   alwaysBoldMode   Comparison	Action
	       ----------------------------------------------------
	       false	  false 	   ignored	use font
	       false	  true		   ignored	use font
	       true	  false 	   same 	overstrike
	       true	  false 	   different	use font
	       true	  true		   ignored	overstrike

       alwaysHighlight (class AlwaysHighlight)
	       Specifies  whether  or  not xterm should always display a highlighted text cursor.
	       By default (if this resource is false), a hollow text cursor is displayed whenever
	       the  pointer  moves  out  of  the window or the window loses the input focus.  The
	       default is ``false.''

       alwaysUseMods (class AlwaysUseMods)
	       Override the numLock resource, telling xterm to use the Alt and Meta modifiers  to
	       construct  parameters for function key sequences even if those modifiers appear in
	       the translations resource.  The default is ``false.''

       answerbackString (class AnswerbackString)
	       Specifies the string that xterm sends in response to an ENQ (control/E)	character
	       from  the  host.   The  default	is  a blank string, i.e., ``''.  A hardware VT100
	       implements this feature as a setup option.

       appcursorDefault (class AppcursorDefault)
	       If ``true,'' the cursor keys are initially in application mode.	This is the  same
	       as the VT102 private DECCKM mode, The default is ``false.''

       appkeypadDefault (class AppkeypadDefault)
	       If  ``true,''  the  keypad keys are initially in application mode.  The default is
	       ``false.''

       autoWrap (class AutoWrap)
	       Specifies whether or not auto-wraparound should be enabled.  This is the  same  as
	       the VT102 DECAWM.  The default is ``true.''

       awaitInput (class AwaitInput)
	       Specifies  whether  or  not the xterm uses a 50 millisecond timeout to await input
	       (i.e., to support the Xaw3d arrow scrollbar).  The default is ``false.''

       backarrowKey (class BackarrowKey)
	       Specifies whether the backarrow key transmits a	backspace(8)	or  delete(127)
	       character.   This  corresponds  to  the	DECBKM	control  sequence.   The  default
	       (backspace) is ``true.''  Pressing the control key toggles this behavior.

       background (class Background)
	       Specifies the color to use for the background  of  the  window.	 The  default  is
	       ``XtDefaultBackground.''

       bellIsUrgent (class BellIsUrgent)
	       Specifies  whether  to  set  the Urgency hint for the window manager when making a
	       bell sound.  The default is ``false.''

       bellOnReset (class BellOnReset)
	       Specifies whether to sound a bell  when	doing  a  hard	reset.	 The  default  is
	       ``true.''

       bellSuppressTime (class BellSuppressTime)
	       Number  of milliseconds after a bell command is sent during which additional bells
	       will be suppressed.  Default is 200.  If set non-zero, additional bells will  also
	       be  suppressed until the server reports that processing of the first bell has been
	       completed; this feature is most useful with the visible bell.

       boldColors (class ColorMode)
	       Specifies whether to combine bold attribute with colors like the IBM PC, i.e., map
	       colors  0  through 7 to colors 8 through 15.  These normally are the brighter ver-
	       sions of the first 8 colors, hence bold.  The default is ``true.''

       boldFont (class BoldFont)
	       Specifies the name of the bold font to use instead of overstriking.  There  is  no
	       default for this resource.

       boldMode (class BoldMode)
	       This specifies whether or not text with the bold attribute should be overstruck to
	       simulate bold fonts if the resolved bold font is the same as the normal font.   It
	       may  be	desirable  to  disable	bold  fonts when color is being used for the bold
	       attribute.

	       Note that xterm has one bold font which you may set explicitly.	Xterm attempts to
	       derive  a  bold	font  for the other font selections (font1 through font6).  If it
	       cannot find a bold font, it will use the normal font.  In each case  (whether  the
	       explicit resource or the derived font), if the normal and bold fonts are distinct,
	       this resource has no effect.  The default is ``true.''

	       See the alwaysBoldMode resource which can modify the behavior of this resource.

	       Although xterm attempts to derive a bold font for other font selections, the  font
	       server  may  not cooperate.  Since X11R6, bitmap fonts have been scaled.  The font
	       server claims to provide the bold font that xterm requests, but the result is  not
	       always  readable.   XFree86  provides  a feature which can be used to suppress the
	       scaling.  In the X server's configuration file (e.g., "/etc/X11/XFree86"), you can
	       add  ":unscaled"  to  the end of the directory specification for the "misc" fonts,
	       which comprise the fixed-pitch fonts that are used by xterm.  For example
		       FontPath 	"/usr/lib/X11/fonts/misc/"

	       would become
		       FontPath 	"/usr/lib/X11/fonts/misc/:unscaled"

	       Depending on your configuration, the font server may have  its  own  configuration
	       file.   The  same ":unscaled" can be added to its configuration file at the end of
	       the directory specification for "misc".

       brokenLinuxOSC (class BrokenLinuxOSC)
	       If true, xterm applies a workaround to ignore malformed control sequences  that	a
	       Linux script might send.  Compare the palette control sequences documented in con-
	       sole_codes with ECMA-48.  The default is ``true.''

       brokenSelections (class BrokenSelections)
	       If true, xterm in 8-bit mode will interpret STRING selections as carrying text  in
	       the  current  locale's  encoding.   Normally  STRING  selections  carry ISO-8859-1
	       encoded text.  Setting this resource to ``true'' violates the ICCCM; it may,  how-
	       ever,  be  useful  for  interacting  with  some	broken X clients.  The default is
	       ``false.''

       brokenStringTerm (class BrokenStringTerm)
	       provides a work-around for some ISDN routers which start  an  application  control
	       string  without	completing  it.   Set this to ``true'' if xterm appears to freeze
	       when connecting.  The default is ``false.''

       c132 (class C132)
	       Specifies whether or not the VT102 DECCOLM escape sequence, used to switch between
	       80 and 132 columns, should be honored.  The default is ``false.''

       cacheDoublesize (class CacheDoublesize)
	       Tells  whether  to cache double-sized fonts by xterm.  Set this to zero to disable
	       doublesize fonts altogether.

       charClass (class CharClass)
	       Specifies  comma-separated  lists  of  character  class	bindings  of   the   form
	       [low-]high:value.   These  are used in determining which sets of characters should
	       be treated the same when doing cut and paste.  See the CHARACTER CLASSES section.

       cjkWidth (class CjkWidth)
	       Specifies whether xterm should follow the traditional East Asian width convention.
	       When turned on, characters with East Asian Ambiguous (A) category in UTR 11 have a
	       column width of 2.  You may have to set this option to ``true'' if you  have  some
	       old  East  Asian  terminal based programs that assume that line-drawing characters
	       have a column width of 2.  If this resource is false, the  mkWidth  resource  con-
	       trols  the  choice  between the system's wcwidth and xterm's built-in tables.  The
	       default is ``false.''

       color0 (class Color0)

       color1 (class Color1)

       color2 (class Color2)

       color3 (class Color3)

       color4 (class Color4)

       color5 (class Color5)

       color6 (class Color6)

       color7 (class Color7)
	       These specify the colors for the ISO-6429 extension.  The  defaults  are,  respec-
	       tively,	black,	red3, green3, yellow3, a customizable dark blue, magenta3, cyan3,
	       and gray90.  The default shades of color are chosen to allow the colors 8-15 to be
	       used as brighter versions.

       color8 (class Color8)

       color9 (class Color9)

       color10 (class Color10)

       color11 (class Color11)

       color12 (class Color12)

       color13 (class Color13)

       color14 (class Color14)

       color15 (class Color15)
	       These  specify the colors for the ISO-6429 extension if the bold attribute is also
	       enabled.  The default resource values are respectively, gray30, red,  green,  yel-
	       low, a customizable light blue, magenta, cyan, and white.

       color16 (class Color16)

       through

       color255 (class Color255)
	       These specify the colors for the 256-color extension.  The default resource values
	       are for colors 16 through 231 to make a 6x6x6 color cube, and colors  232  through
	       255 to make a grayscale ramp.

       colorAttrMode (class ColorAttrMode)
	       Specifies whether colorBD, colorBL, colorRV, and colorUL should override ANSI col-
	       ors.  If not, these are displayed only when no ANSI colors have been set  for  the
	       corresponding position.	The default is ``false.''

       colorBD (class ColorBD)
	       This  specifies the color to use to display bold characters if the ``colorBDMode''
	       resource is enabled.  The default is ``XtDefaultForeground.''

       colorBDMode (class ColorAttrMode)
	       Specifies whether characters with the bold attribute should be displayed in  color
	       or  as  bold  characters.   Note  that  setting colorMode off disables all colors,
	       including bold.	The default is ``false.''

       colorBL (class ColorBL)
	       This specifies the color to use to display blink characters if the ``colorBLMode''
	       resource is enabled.  The default is ``XtDefaultForeground.''

       colorBLMode (class ColorAttrMode)
	       Specifies  whether  characters  with  the  blink  attribute should be displayed in
	       color.  Note that setting colorMode off disables all colors, including this.   The
	       default is ``false.''

       colorMode (class ColorMode)
	       Specifies  whether  or  not  recognition  of  ANSI  (ISO-6429) color change escape
	       sequences should be enabled.  The default is ``true.''

       colorRV (class ColorRV)
	       This specifies the color to use to display reverse characters  if  the  ``colorRV-
	       Mode'' resource is enabled.  The default is ``XtDefaultForeground.''

       colorRVMode (class ColorAttrMode)
	       Specifies  whether  characters  with  the reverse attribute should be displayed in
	       color.  Note that setting colorMode off disables all colors, including this.   The
	       default is ``false.''

       colorUL (class ColorUL)
	       This  specifies	the  color  to use to display underlined characters if the ``col-
	       orULMode'' resource is enabled.	The default is ``XtDefaultForeground.''

       colorULMode (class ColorAttrMode)
	       Specifies whether characters with the underline attribute should be  displayed  in
	       color  or  as underlined characters.  Note that setting colorMode off disables all
	       colors, including underlining.  The default is ``false.''

       combiningChars (class CombiningChars)
	       Specifies the number of wide-characters which can be stored in  a  cell	to  over-
	       strike  (combine)  with the base character of the cell.	This can be set to values
	       in the range 0 to 4.  The default is ``2''.

       ctrlFKeys (class CtrlFKeys)
	       In VT220 keyboard mode (see sunKeyboard resource), specifies the amount	by  which
	       to  shift F1-F12 given a control modifier (CTRL).  This allows you to generate key
	       symbols for F10-F20 on a Sun/PC keyboard.  The default is ``10'', which means that
	       CTRL F1 generates the key symbol for F11.

       curses (class Curses)
	       Specifies  whether  or not the last column bug in more(1) should be worked around.
	       See the -cu option for details.	The default is ``false.''

       cursorBlink (class CursorBlink)
	       Specifies whether to make the cursor blink.  The default is ``false.''

       cursorColor (class CursorColor)
	       Specifies the color to use for the text cursor.	The default  is  ``XtDefaultFore-
	       ground.''   By  default,  xterm attempts to keep this color from being the same as
	       the background color, since it draws the cursor by filling  the	background  of	a
	       text  cell.   The  same	restriction applies to control sequences which may change
	       this color.

	       Setting this resource overrides most of xterm's adjustments to cursor  color.   It
	       will  still  use reverse-video to disallow some cases, such as a black cursor on a
	       black background.

       cursorOffTime (class CursorOffTime)
	       Specifies the duration of the "off" part of the cursor blink  cycle-time  in  mil-
	       liseconds.  The same timer is used for text blinking.  The default is 300.

       cursorOnTime (class CursorOnTime)
	       Specifies  the  duration  of the "on" part of the cursor blink cycle-time, in mil-
	       liseconds.  The same timer is used for text blinking.  The default is 600.

       cutNewline (class CutNewline)
	       If ``false'', triple clicking to select a line does not include the Newline at the
	       end of the line.  If ``true'', the Newline is selected.	The default is ``true.''

       cursorUnderLine (class CursorUnderLine)
	       Specifies  whether  to  make  the  cursor  underlined  or  a  box.  The default is
	       ``false.''

       cutToBeginningOfLine (class CutToBeginningOfLine)
	       If ``false'', triple clicking to select a line selects only from the current  word
	       forward.  If ``true'', the entire line is selected.  The default is ``true.''

       decTerminalID (class DecTerminalID)
	       Specifies  the emulation level (100=VT100, 220=VT220, etc.), used to determine the
	       type of response to a DA  control  sequence.   Leading  non-digit  characters  are
	       ignored, e.g., "vt100" and "100" are the same.  The default is 100.

       deleteIsDEL (class DeleteIsDEL)
	       Specifies  whether  the	Delete key on the editing keypad should send DEL(127) or
	       the VT220-style Remove escape sequence.	The default is ``false,'' for the latter.

       dynamicColors (class DynamicColors)
	       Specifies whether or not escape sequences to change colors assigned  to	different
	       attributes are recognized.

       eightBitControl (class EightBitControl)
	       Specifies  whether  or not control sequences sent by the terminal should be eight-
	       bit characters or escape sequences.  The default is ``false.''

       eightBitInput (class EightBitInput)
	       If ``true'', Meta characters (a single-byte character combined with the Meta modi-
	       fier  key)  input  from	the keyboard are presented as a single character with the
	       eighth bit turned on.  The terminal is put into 8-bit mode.   If  ``false'',  Meta
	       characters  are	converted into a two-character sequence with the character itself
	       preceded by ESC.  On startup, xterm tries to put the  terminal  into  7-bit  mode.
	       The  metaSendsEscape  and altSendsEscape resources may override this.  The default
	       is ``true.''

	       Generally keyboards do not have a key labeled "Meta", but "Alt" keys  are  common,
	       and  they  are  conventionally used for "Meta".	If they were synonymous, it would
	       have been reasonable to name this resource "altSendsEscape", reversing its  sense.
	       For more background on this, see the meta function in curses.

	       Note  that  the Alt key is not necessarily the same as the Meta modifier.  xmodmap
	       lists your key modifiers.  X defines modifiers for shift, (caps) lock and control,
	       as  well as 5 additional modifiers which are generally used to configure key modi-
	       fiers.  xterm inspects the same information to find the modifier  associated  with
	       either  Meta key (left or right), and uses that key as the Meta modifier.  It also
	       looks for the NumLock key, to recognize the  modifier  which  is  associated  with
	       that.

	       If your xmodmap configuration uses the same keycodes for Alt- and Meta-keys, xterm
	       will only see the Alt-key definitions, since those are  tested  before  Meta-keys.
	       NumLock	is  tested first.  It is important to keep these keys distinct; otherwise
	       some of xterm's functionality is not available.

       eightBitOutput (class EightBitOutput)
	       Specifies whether or not  eight-bit  characters	sent  from  the  host  should  be
	       accepted  as  is  or  stripped when printed.  The default is ``true,'' which means
	       that they are accepted as is.

       faceName (class FaceName)
	       Specify the pattern for fonts selected from the FreeType library  if  support  for
	       that  library was compiled into xterm.  There is no default.  If not specified, or
	       if there is no match for both normal and bold  fonts,  xterm  uses  the	font  and
	       related resources.

       faceNameDoublesize (class FaceNameDoublesize)
	       Specify	an  double-width font for cases where an application requires this, e.g.,
	       in CJK applications.  There is no default.  If the  application	uses  double-wide
	       characters and this resource is not given, xterm  will use a scaled version of the
	       font given by faceName.

       faceSize (class FaceSize)
	       Specify the pointsize for fonts selected from the FreeType library if support  for
	       that  library  was  compiled  into xterm.  The default is ``14.''  On the VT Fonts
	       menu, this corresponds to the Default entry.

	       You can specify the pointsize for TrueType fonts selected  with	the  other  size-
	       related	menu  entries  such  as Medium, Huge, etc., by using one of the following
	       resource values.  If you do not specify a value, they default  to  ``0.0'',  which
	       causes  xterm  to  use  the ratio of font sizes from the corresponding bitmap font
	       resources to obtain a TrueType pointsize.

	       If all of the faceSize resources are set, then xterm will use this information  to
	       determine  the  next  smaller/larger  TrueType  font  for the larger-vt-font() and
	       smaller-vt-font() actions.  If any are not set, xterm will use only the	areas  of
	       the bitmap fonts.

       faceSize1 (class FaceSize1)
	       Specifies the pointsize of the first alternative font.

       faceSize2 (class FaceSize2)
	       Specifies the pointsize of the second alternative font.

       faceSize3 (class FaceSize3)
	       Specifies the pointsize of the third alternative font.

       faceSize4 (class FaceSize4)
	       Specifies the pointsize of the fourth alternative font.

       faceSize5 (class FaceSize5)
	       Specifies the pointsize of the fifth alternative font.

       faceSize6 (class FaceSize6)
	       Specifies the pointsize of the sixth alternative font.

       font (class Font)
	       Specifies the name of the normal font.  The default is ``fixed.''

	       See  the  discussion  of the locale resource, which describes how this font may be
	       overridden.

	       NOTE: some resource files use patterns such as
	       *font: fixed

	       which are overly broad, affecting both
	       xterm.vt100.font

	       and
	       xterm.vt100.utf8fonts.font

	       which is probably not what you intended.

       font1 (class Font1)
	       Specifies the name of the first alternative font.

       font2 (class Font2)
	       Specifies the name of the second alternative font.

       font3 (class Font3)
	       Specifies the name of the third alternative font.

       font4 (class Font4)
	       Specifies the name of the fourth alternative font.

       font5 (class Font5)
	       Specifies the name of the fifth alternative font.

       font6 (class Font6)
	       Specifies the name of the sixth alternative font.

       fontDoublesize (class FontDoublesize)
	       Specifies whether xterm should attempt to use  font  scaling  to  draw  doublesize
	       characters.  Some older font servers cannot do this properly, will return mislead-
	       ing font metrics.  The default is ``true''.  If disabled, xterm will simulate dou-
	       blesize characters by drawing normal characters with spaces between them.

       fontWarnings (class FontWarnings)
	       Specify whether xterm should report an error if it fails to load a font:

	       0    Never report an error (though the X libraries may).

	       1    Report an error if the font name was given as a resource setting.

	       2    Always report an error on failure to load a font.

       forceBoxChars (class ForceBoxChars)
	       Specifies  whether  xterm should assume the normal and bold fonts have VT100 line-
	       drawing characters:

	       -    The fixed-pitch ISO-8859-*-encoded fonts used  by  xterm  normally	have  the
		    VT100 line-drawing glyphs in cells 1-31.  Other fixed-pitch fonts may be more
		    attractive, but lack these glyphs.

	       -    When using an ISO-10646-1 font and the wideChars resource is true, xterm uses
		    the Unicode glyphs which match the VT100 line-drawing glyphs.

	       If  ``false'',  xterm checks for missing glyphs in the font and makes line-drawing
	       characters directly as needed.  If ``true'', xterm assumes the font does not  con-
	       tain  the  line-drawing	characters,  and  draws  them  directly.   The default is
	       ``false.''

       foreground (class Foreground)
	       Specifies the color to use for displaying text in the window.  Setting  the  class
	       name  instead  of  the  instance name is an easy way to have everything that would
	       normally appear in the text color change color.	The default  is  ``XtDefaultFore-
	       ground.''

       formatOtherKeys (class FormatOtherKeys)
	       Overrides  the format of the escape sequence used to report modified keys with the
	       modifyOtherKeys resource.

	       0  send modified keys as parameters for function-key 27 (default).

	       1  send modified keys as parameters for CSI u.

       freeBoldBox (class FreeBoldBox)
	       Specifies whether xterm should assume the bounding boxes for normal and bold fonts
	       are compatible.	If ``false'', xterm compares them and will reject choices of bold
	       fonts that do not match the size of the normal font.  The  default  is  ``false'',
	       which means that the comparison is performed.

       geometry (class Geometry)
	       Specifies  the  preferred  size	and  position  of  the VT102 window.  There is no
	       default for this resource.

       highlightColor (class HighlightColor)
	       Specifies the color to use for the background of selected (highlighted) text.   If
	       not specified (i.e., matching the default foreground), reverse video is used.  The
	       default is ``XtDefaultForeground.''

       highlightColorMode (class HighlightColorMode)
	       Specifies whether xterm should use highlightTextColor and highlightColor to  over-
	       ride  the  reversed  foreground/background  colors in a selection.  The default is
	       unspecified: at startup, xterm checks if those  resources  are  set  to	something
	       other  than  the  default foreground and background colors.  Setting this resource
	       disables the check.

	       The following table shows the interaction of the highlighting resources,  abbrevi-
	       ated as shown to fit in this page:

	       HCM
		  highlightColorMode

	       HR highlightReverse

	       HBG
		  highlightColor

	       HFG
		  highlightTextColor

	       default	 true	 set	   set	     HFG/HBG
	       ------------------------------------------------------

       highlightReverse (class HighlightReverse)
	       Specifies  whether  xterm  should  reverse the selection foreground and background
	       colors when selecting text with reverse-video attribute.  This applies only to the
	       highlightColor  and  highlightTextColor resources, e.g., to match the color scheme
	       of xwsh.  If ``true'', xterm reverses the colors, If  ``false'',  xterm	does  not
	       reverse colors, The default is ``true.''

       highlightSelection (class HighlightSelection)
	       If  ``false'',  selecting  with	the  mouse highlights all positions on the screen
	       between the beginning of the selection and the  current	position.   If	``true'',
	       xterm  highlights  only the positions that contain text that can be selected.  The
	       default is ``false.''

	       Depending on the way your applications write to the screen, there may be  trailing
	       blanks  on  a  line.  Xterm stores data as it is shown on the screen.  Erasing the
	       display changes the internal state of each cell so it is not  considered  a  blank
	       for the purpose of selection.  Blanks written since the last erase are selectable.
	       If you do not wish to have trailing blanks in a selection, use  the  trimSelection
	       resource.

       highlightTextColor (class HighlightTextColor)
	       Specifies  the color to use for the foreground of selected (highlighted) text.  If
	       not specified (i.e., matching the default background), reverse video is used.  The
	       default is ``XtDefaultBackground.''

       hpLowerleftBugCompat (class HpLowerleftBugCompat)
	       Specifies  whether  to  work  around  a bug in HP's xdb, which ignores termcap and
	       always sends ESC F to move to the lower left corner.   ``true''	causes	xterm  to
	       interpret  ESC F as a request to move to the lower left corner of the screen.  The
	       default is ``false.''

       i18nSelections (class I18nSelections)
	       If false, xterm will never request the targets COMPOUND_TEXT or TEXT.  The default
	       is  ``true.''  It  may be set to false in order to work around ICCCM violations by
	       other X clients.

       iconBorderColor (class BorderColor)
	       Specifies the border color for the active icon window if this feature is  compiled
	       into xterm.  Not all window managers will make the icon border visible.

       iconBorderWidth (class BorderWidth)
	       Specifies  the border width for the active icon window if this feature is compiled
	       into xterm.  The default is 2.  Not all window managers will make the border visi-
	       ble.

       iconFont (class IconFont)
	       Specifies  the  font for the miniature active icon window, if this feature is com-
	       piled into xterm.  The default is "nil2".

       initialFont (class InitialFont)
	       Specifies which of the VT100 fonts to use initially.  Values are the same  as  for
	       the set-vt-font action.	The default is ``d'', i.e., "default".

       inputMethod (class XtCInputMethod)
	       Tells xterm which type of input method to use.  There is no default method.

       internalBorder (class BorderWidth)
	       Specifies  the number of pixels between the characters and the window border.  The
	       default is 2.

       italicULMode (class ColorAttrMode)
	       Specifies whether characters with the underline attribute should be  displayed  in
	       an  italic  font or as underlined characters.  It is implemented only for TrueType
	       fonts.

       jumpScroll (class JumpScroll)
	       Specifies whether or not jump scroll should be  used.   This  corresponds  to  the
	       VT102 DECSCLM private mode.  The default is ``true.''

       keepSelection (class KeepSelection)
	       Specifies  whether  xterm will keep the selection even after the selected area was
	       touched by some output to the terminal.	The default is ``false''.

       keyboardDialect (class KeyboardDialect)
	       Specifies the initial keyboard dialect, as well as the default value when the ter-
	       minal is reset.	The value given is the same as the final character in the control
	       sequences which change character sets.  The default is ``B'', which corresponds to
	       US ASCII.

       nameKeymap (class NameKeymap)
	       See the discussion of the keymap() action.

       limitResize (class LimitResize)
	       Limits resizing of the screen via control sequence to a given multiple of the dis-
	       play dimensions.  The default is ``1''.

       locale (class Locale)
	       Specifies how to use luit, an encoding converter between UTF-8 and  locale  encod-
	       ings.  The resource value (ignoring case) may be:

	       true
		   xterm  will	use  the  encoding specified by the users' LC_CTYPE locale (i.e.,
		   LC_ALL, LC_CTYPE, or LANG variables) as far as possible.  This is realized  by
		   always enabling UTF-8 mode and invoking luit in non-UTF-8 locales.

	       medium
		   xterm  will follow users' LC_CTYPE locale only for UTF-8, east Asian, and Thai
		   locales, where the encodings were not supported by conventional 8bit mode with
		   changing fonts.  For other locales, xterm will use conventional 8bit mode.

	       checkfont
		   If mini-luit is compiled-in, xterm will check if a Unicode font has been spec-
		   ified.  If so, it checks if the character encoding for the current  locale  is
		   POSIX,  Latin-1 or Latin-9, uses the appropriate mapping to support those with
		   the Unicode font.  For other encodings, xterm assumes that UTF-8  encoding  is
		   required.

	       false
		   xterm will use conventional 8bit mode or UTF-8 mode according to utf8 resource
		   or -u8 option.

	       Any other value, e.g., ``UTF-8'' or ``ISO8859-2'', is assumed to  be  an  encoding
	       name;  luit will be invoked to support the encoding.  The actual list of supported
	       encodings depends on luit.  The default is ``medium''.

	       Regardless of your locale and encoding, you need an ISO-10646-1	font  to  display
	       the  result.   Your  configuration may not include this font, or locale-support by
	       xterm may not be needed.  At startup, xterm uses a  mechanism  equivalent  to  the
	       load-vt-fonts(utf8Fonts, Utf8Fonts)  action  to load font name subresources of the
	       VT100 widget.  That is, resource patterns such as "*vt100.utf8Fonts.font" will  be
	       loaded,	and (if this resource is enabled), override the normal fonts.  If no sub-
	       resources are found, the normal fonts such as "*vt100.font", etc., are used.   The
	       resource  files	distributed  with xterm use ISO-10646-1 fonts, but do not rely on
	       them unless you are using the locale mechanism.

       localeFilter (class LocaleFilter)
	       Specifies the file name for the encoding converter from/to  locale  encodings  and
	       UTF-8  which  is  used  with  the -lc option or locale resource.  The help message
	       shown by ``xterm -help'' lists the default value, which	depends  on  your  system
	       configuration.

	       If  the	encoding converter requires command-line parameters, you should put those
	       within a shell script to execute the converter, and set this resource to point  to
	       the shell script.

       loginShell (class LoginShell)
	       Specifies  whether or not the shell to be run in the window should be started as a
	       login shell.  The default is ``false.''

       marginBell (class MarginBell)
	       Specifies whether or not the bell should be rung when  the  user  types	near  the
	       right margin.  The default is ``false.''

       metaSendsEscape (class MetaSendsEscape)
	       If ``true'', Meta characters (a character combined with the Meta modifier key) are
	       converted into a two-character sequence with the character itself preceded by ESC.
	       This  applies  as  well	to function key control sequences, unless xterm sees that
	       Meta is used in your key translations.  If ``false'', Meta characters  input  from
	       the  keyboard are handled according to the eightBitInput resource.  The default is
	       ``false.''

       mkSamplePass (class MkSamplePass)
	       If mkSampleSize is nonzero, and mkWidth (and cjkWidth) are false, on startup xterm
	       compares  its  built-in tables to the system's wide character width data to decide
	       if it will use the system's data.  It tests the first mkSampleSize character  val-
	       ues,  and allows up to mkSamplePass mismatches before the test fails.  The default
	       (for the allowed number of mismatches) is 256.

       mkSampleSize (class MkSampleSize)
	       With mkSamplePass, this specifies a startup test used for initializing wide  char-
	       acter width calculations.  The default (number of characters to check) is 1024.

       mkWidth (class MkWidth)
	       Specifies  whether xterm should use a built-in version of the wide character width
	       calculation.  See also the cjkWidth resource which can override this.  The default
	       is ``false.''

	       Here  is  a  summary  of  the resources which control the choice of wide character
	       width calculation:

	       cjkWidth   mkWidth   Action
	       ---------------------------------------------------------------
	       false	  false     use system tables subject to mkSamplePass
	       false	  true	    use built-in tables
	       true	  false     use built-in CJK tables
	       true	  true	    use built-in CJK tables

       modifyCursorKeys (class ModifyCursorKeys)
	       Tells how to handle the special case where Control-, Shift-,  Alt-  or  Meta-modi-
	       fiers are used to add a parameter to the escape sequence returned by a cursor-key.
	       The default is ``2'':

	       Set it to -1 to disable it.
	       Set it to 0 to use the old/obsolete behavior.
	       Set it to 1 to prefix modified sequences with CSI.
	       Set it to 2 to force the modifier to be the second parameter if it would otherwise
	       be the first.
	       Set it to 3 to mark the sequence with a '>' to hint that it is private.

       modifyFunctionKeys (class ModifyFunctionKeys)
	       Tells  how  to  handle the special case where Control-, Shift-, Alt- or Meta-modi-
	       fiers are used to add a parameter to the escape sequence returned by a  (numbered)
	       function-key.   The  default is ``2''.  The resource values are similar to modify-
	       CursorKeys:

	       Set it to -1 to permit the user to use shift- and control-modifiers  to	construct
	       function-key strings using the normal encoding scheme.
	       Set it to 0 to use the old/obsolete behavior.
	       Set it to 1 to prefix modified sequences with CSI.
	       Set it to 2 to force the modifier to be the second parameter if it would otherwise
	       be the first.
	       Set it to 3 to mark the sequence with a '>' to hint that it is private.

	       If modifyFunctionKeys is zero, xterm uses Control- and  Shift-modifiers	to  allow
	       the  user  to construct numbered function-keys beyond the set provided by the key-
	       board:

	       Control
		    adds the value given by the ctrlFKeys resource.

	       Shift
		    adds twice the value given by the ctrlFKeys resource.

	       Control/Shift
		    adds three times the value given by the ctrlFKeys resource.

	       As a special case, legacy (when oldFunctionKeys is true) or  vt220  (when  sunKey-
	       board  is  true)  keyboards  interpret only the Control-modifier when constructing
	       numbered function-keys.	This is done to  provide  compatible  keyboards  for  DEC
	       VT220 and related terminals that implement user-defined keys (UDK).

       modifyOtherKeys (class ModifyOtherKeys)
	       Like  modifyCursorKeys, tells xterm to construct an escape sequence for other keys
	       (such as "2") when modified by Control-, Alt-  or  Meta-modifiers.   This  feature
	       does  not  apply to function keys and well-defined keys such as ESC or the control
	       keys.  The default is ``0'':

	       0    disables this feature.

	       1    enables this feature for keys except  for  those  with  well-known	behavior,
		    e.g., Tab, Backarrow and some special control character cases, e.g., Control-
		    Space to make a NUL.

	       2    enables this feature for keys including the exceptions listed.

       multiClickTime (class MultiClickTime)
	       Specifies the maximum time in milliseconds between multi-click select events.  The
	       default is 250 milliseconds.

       multiScroll (class MultiScroll)
	       Specifies  whether or not scrolling should be done asynchronously.  The default is
	       ``false.''

       nMarginBell (class Column)
	       Specifies the number of characters from the right margin at which the margin  bell
	       should be rung, when enabled by the marginBell resource.  The default is 10.

       numLock (class NumLock)
	       If  ``true'',  xterm checks if NumLock is used as a modifier (see xmodmap(1)).  If
	       so, this modifier is used to simplify the logic when implementing special  NumLock
	       for  the sunKeyboard resource.  Also (when sunKeyboard is false), similar logic is
	       used to find the modifier associated with  the  left  and  right  Alt  keys.   The
	       default is ``true.''

       oldXtermFKeys (class OldXtermFKeys)
	       If  ``true'',  xterm  will use old-style control sequences for function keys F1 to
	       F4, for compatibility with X Consortium xterm.  Otherwise, it uses the VT100-style
	       codes for PF1 to PF4.  The default is ``false.''

       on2Clicks (class On2Clicks)

       on3Clicks (class On3Clicks)

       on4Clicks (class On4Clicks)

       on5Clicks (class On5Clicks)
	       Specify	selection  behavior in response to multiple mouse clicks.  A single mouse
	       click is always interpreted as described in the	SELECTION  section  (see  POINTER
	       USAGE).	 Multiple mouse clicks (using the button which activates the select-start
	       action) are interpreted according to the resource values of on2Clicks,  etc.   The
	       resource value can be one of these:

	       word
		  Select  a  ``word'' as determined by the charClass resource.	See the CHARACTER
		  CLASSES section.

	       line
		  Select a line (counting wrapping).

	       group
		  Select a group of adjacent lines (counting wrapping).  The selection stops on a
		  blank line.

	       page
		  Select all visible lines, i.e., the page.

	       all
		  Select all lines, i.e., including the saved lines.

	       regex
		  Select  a ``word'' as determined by the regular expression which follows in the
		  resource value.

	       none
		  No selection action is associated with this resource.  xterm interprets  it  as
		  the  end  of	the  list.   For  example,  you may use it to disable triple (and
		  higher) clicking by setting on3Clicks to ``none''.

	       The default values for on2Clicks and on3Clicks are ``word'' and ``line'',  respec-
	       tively.	 There is no default value for on4Clicks or on5Clicks, making those inac-
	       tive.  On startup, xterm determines the maximum number of clicks by the	onXClicks
	       resource values which are set.

       openIm (class XtCOpenIm)
	       Tells xterm whether to open the input method at startup.  The default is ``true''.

       pointerColor (class PointerColor)
	       Specifies  the  foreground  color of the pointer.  The default is ``XtDefaultFore-
	       ground.''

       pointerColorBackground (class PointerColorBackground)
	       Specifies the background color of the pointer.  The  default  is  ``XtDefaultBack-
	       ground.''

       pointerMode (class PointerMode)
	       Specifies  when	the  pointer  may be hidden as the user types.	It will be redis-
	       played if the user moves the mouse, or clicks one of its buttons.

	       0  never

	       1  the application running in xterm has not activated mouse  mode.   This  is  the
		  default.

	       2  always.

       pointerShape (class Cursor)
	       Specifies the name of the shape of the pointer.	The default is ``xterm.''

       popOnBell (class PopOnBell)
	       Specifies  whether  the	window	would  be raised when Control-G is received.  The
	       default is ``false.''

       preeditType (class XtCPreeditType)
	       Tells xterm which types of preedit (preconversion) string to display.  The default
	       is ``OverTheSpot,Root''.

       printAttributes (class PrintAttributes)
	       Specifies  whether  to  print  graphic attributes along with the text.  A real DEC
	       VTxxx terminal will print the underline, highlighting codes but your  printer  may
	       not handle these.  A ``0'' disables the attributes.  A ``1'' prints the normal set
	       of  attributes  (bold,  underline,  inverse  and  blink)  as  VT100-style  control
	       sequences.  A ``2'' prints ANSI color attributes as well.  The default is ``1.''

       printerAutoClose (class PrinterAutoClose)
	       If  ``true'',  xterm will close the printer (a pipe) when the application switches
	       the printer offline with a Media Copy command.  The default is ``false.''

       printerCommand (class PrinterCommand)
	       Specifies a shell command to which xterm will open a pipe when the first MC (Media
	       Copy) command is initiated.  The default is a blank string.  If the resource value
	       is given as a blank string, the printer is disabled.

       printerControlMode (class PrinterControlMode)
	       Specifies the printer control mode.  A ``1'' selects autoprint mode, which  causes
	       xterm  to print a line from the screen when you move the cursor off that line with
	       a line feed, form feed or vertical tab character, or an	autowrap  occurs.   Auto-
	       print mode is overridden by printer controller mode (a ``2''), which causes all of
	       the output to be directed to the printer.  The default is ``0.''

       printerExtent (class PrinterExtent)
	       Controls whether a print page function will print the entire page (true), or  only
	       the the portion within the scrolling margins (false).  The default is ``false.''

       printerFormFeed (class PrinterFormFeed)
	       Controls  whether  a  form  feed is sent to the printer at the end of a print page
	       function.  The default is ``false.''

       quietGrab (class QuietGrab)
	       Controls whether the cursor is repainted when NotifyGrab  and  NotifyUngrab  event
	       types are received during change of focus.  The default is ``false.''

       renderFont (class RenderFont)
	       If  xterm  is  built  with  the	Xft  library,  this controls whether the faceName
	       resource is used.  The default is ``true.''

       resizeGravity (class ResizeGravity)
	       Affects the behavior when the window is resized to be taller or	shorter.   North-
	       West  specifies that the top line of text on the screen stay fixed.  If the window
	       is made shorter, lines are dropped from the bottom; if the window is made  taller,
	       blank  lines are added at the bottom.  This is compatible with the behavior in R4.
	       SouthWest (the default) specifies that the bottom line of text on the screen  stay
	       fixed.  If the window is made taller, additional saved lines will be scrolled down
	       onto the screen; if the window is made shorter, lines will be scrolled off the top
	       of the screen, and the top saved lines will be dropped.

       reverseVideo (class ReverseVideo)
	       Specifies  whether  or  not  reverse  video  should  be simulated.  The default is
	       ``false.''

       reverseWrap (class ReverseWrap)
	       Specifies whether or not reverse-wraparound should be enabled.	This  corresponds
	       to xterm's private mode 45.  The default is ``false.''

       rightScrollBar (class RightScrollBar)
	       Specifies  whether  or  not  the scrollbar should be displayed on the right rather
	       than the left.  The default is ``false.''

       saveLines (class SaveLines)
	       Specifies the number of lines to save beyond the top of the screen when a  scroll-
	       bar is turned on.  The default is 64.

       scrollBar (class ScrollBar)
	       Specifies  whether  or  not  the  scrollbar  should  be displayed.  The default is
	       ``false.''

       scrollBarBorder (class ScrollBarBorder)
	       Specifies the width of the scrollbar border.  Note that this is drawn  to  overlap
	       the border of the xterm window.	Modifying the scrollbar's border affects only the
	       line between the VT100 widget and the scrollbar.  The default value is 1.

       scrollKey (class ScrollCond)
	       Specifies whether or not pressing a key should automatically cause  the	scrollbar
	       to  go to the bottom of the scrolling region.  This corresponds to xterm's private
	       mode 1011.  The default is ``false.''

       scrollLines (class ScrollLines)
	       Specifies the number of lines that the scroll-back and scroll-forw actions  should
	       use as a default.  The default value is 1.

       scrollTtyOutput (class ScrollCond)
	       Specifies  whether  or  not  output to the terminal should automatically cause the
	       scrollbar to go to the bottom of the scrolling region.  The default is ``true.''

       selectToClipboard (class SelectToClipboard)
	       Tells xterm whether to use the PRIMARY or  CLIPBOARD  for  SELECT  tokens  in  the
	       selection  mechanism.   The set-select action can change this at runtime, allowing
	       the user to work with programs that handle only	one  of  these	mechanisms.   The
	       default is ``false'', which tells it to use PRIMARY.

       shiftFonts (class ShiftFonts)
	       Specifies  whether  to  enable the actions larger-vt-font() and smaller-vt-font(),
	       which are normally bound to the shifted KP_Add and KP_Subtract.	 The  default  is
	       ``true.''

       showBlinkAsBold (class ShowBlinkAsBold)
	       Tells  xterm  whether  to  display text with blink-attribute the same as bold.  If
	       xterm has not been configured to support blinking text, the default is  ``true.'',
	       which corresponds to older versions of xterm, otherwise the default is ``false.''

       showMissingGlyphs (class ShowMissingGlyphs)
	       Tells  xterm  whether to display a box outlining places where a character has been
	       used that the font does not represent.  The default is ``false.''

       signalInhibit (class SignalInhibit)
	       Specifies whether or not the entries in the ``Main Options'' menu for sending sig-
	       nals to xterm should be disallowed.  The default is ``false.''

       tekGeometry (class Geometry)
	       Specifies  the  preferred  size and position of the Tektronix window.  There is no
	       default for this resource.

       tekInhibit (class TekInhibit)
	       Specifies whether or not the escape sequence to enter  Tektronix  mode  should  be
	       ignored.  The default is ``false.''

       tekSmall (class TekSmall)
	       Specifies  whether  or  not the Tektronix mode window should start in its smallest
	       size if no explicit geometry is given.  This is useful when running xterm on  dis-
	       plays with small screens.  The default is ``false.''

       tekStartup (class TekStartup)
	       Specifies  whether or not xterm should start up in Tektronix mode.  The default is
	       ``false.''

       tiXtraScroll (class TiXtraScroll)
	       Specifies whether xterm should scroll to a new page when processing the ti termcap
	       entry,  i.e.,  the  private  modes  47,	1047  or 1049.	This is only in effect if
	       titeInhibit is ``true'', because the intent of this option is to provide a picture
	       of  the full-screen application's display on the scrollback without wiping out the
	       text that would be shown before the application was initialized.  The default  for
	       this resource is ``false.''

       titeInhibit (class TiteInhibit)
	       Specifies  whether  or  not xterm should remove ti and te termcap entries (used to
	       switch between alternate screens on startup of many screen-oriented programs) from
	       the  TERMCAP  string.  If set, xterm also ignores the escape sequence to switch to
	       the alternate screen.  Xterm supports terminfo in a different way, supporting com-
	       posite  control	sequences (also known as private modes) 1047, 1048 and 1049 which
	       have the same effect as the original 47 control sequence.  The  default	for  this
	       resource is ``false.''

       translations (class Translations)
	       Specifies  the  key  and  button  bindings  for	menus,	selections,  ``programmed
	       strings,'' etc.	The translations resource, which provides much of xterm's config-
	       urability, is a feature of the X Toolkit Intrinsics library (Xt).  See the ACTIONS
	       section.

       trimSelection (class TrimSelection)
	       If you set highlightSelection, you can see the text which is  selected,	including
	       any  trailing  spaces.	Clearing the screen (or a line) resets it to a state con-
	       taining no spaces.  Some lines may contain trailing  spaces  when  an  application
	       writes them to the screen.  However, you may not wish to paste lines with trailing
	       spaces.	If this resource is true, xterm will trim trailing spaces from text which
	       is  selected.   It does not affect spaces which result in a wrapped line, nor will
	       it trim the trailing newline from your selection.  The default is ``false.''

       underLine (class UnderLine)
	       This specifies whether or not text with the underline attribute should  be  under-
	       lined.	It  may  be desirable to disable underlining when color is being used for
	       the underline attribute.  The default is ``true.''

       useClipping (class UseClipping)
	       Tell xterm whether to use clipping to keep from producing dots  outside	the  text
	       drawing	area.	Originally  used to work around for overstriking effects, this is
	       also needed to work with some incorrectly-sized fonts.  The default is ``true.''

       utf8 (class Utf8)
	       This specifies whether xterm will run in UTF-8 mode.  If you  set  this	resource,
	       xterm also sets the wideChars resource as a side-effect.  The resource is an inte-
	       ger, expected to range from 0 to 3:

	       0  UTF-8 mode is initially off.	The command-line option +u8 sets the resource  to
		  this value.  Escape sequences for turning UTF-8 mode on/off are allowed.

	       1  UTF-8 mode is initially on.  Escape sequences for turning UTF-8 mode on/off are
		  allowed.

	       2  The command-line option -u8 sets the resource to this value.	Escape	sequences
		  for turning UTF-8 mode on/off are ignored.

	       3  This is the default value of the resource.  It is changed during initialization
		  depending on whether the locale resource was set, to 0 or 2.	 See  the  locale
		  resource for additional discussion of non-UTF-8 locales.

	       If  you	want to set the value of utf8, it should be in this range.  Other nonzero
	       values are treated the same as ``1'', i.e., UTF-8 mode is initially on, and escape
	       sequences for turning UTF-8 mode on/off are allowed.

       utf8Fonts (class Utf8Fonts)
	       See the discussion of the locale resource.

       utf8Latin1 (class Utf8Latin1)
	       If  true, allow an ISO-8859-1 normal font to be combined with an ISO-10646 font if
	       the latter is given via the -fw option or its corresponding resource  value.   The
	       default is ``false.''

       utf8Title (class Utf8Title)
	       Applications  can  set xterm's title by writing a control sequence.  Normally this
	       control sequence follows  the  VT220  convention,  which  encodes  the  string  in
	       ISO-8859-1  and	allows	for an 8-bit string terminator.  If xterm is started in a
	       UTF-8 locale, it translates the ISO-8859-1 string to UTF-8  to  work  with  the	X
	       libraries which assume the string is UTF-8.

	       However,  some  users may wish to write a title string encoded in UTF-8.  Set this
	       resource to ``true'' to allow UTF-8  encoded  title  strings.   That  cancels  the
	       translation to UTF-8, allowing UTF-8 strings to be displayed as is.

	       The default is ``false.''

       veryBoldColors (class VeryBoldColors)
	       Specifies  whether  to  combine video attributes with colors specified by colorBD,
	       colorBL, colorRV and colorUL.  The resource value is the sum of	values	for  each
	       attribute:
		 1 for reverse,
		 2 for underline,
		 4 for bold and
		 8 for blink.

	       The default is ``0.''

       visualBell (class VisualBell)
	       Specifies whether or not a visible bell (i.e., flashing) should be used instead of
	       an audible bell when Control-G is received.  The default is ``false.''

       visualBellDelay (class VisualBellDelay)
	       Number of milliseconds to delay when displaying a visual bell.	Default  is  100.
	       If  set	to  zero, no visual bell is displayed.	This is useful for very slow dis-
	       plays, e.g., an LCD display on a laptop.

       vt100Graphics (class VT100Graphics)
	       This specifies  whether	xterm  will  interpret	VT100  graphic	character  escape
	       sequences  while  in  UTF-8 mode.  The default is ``true'', to provide support for
	       various legacy applications.

       wideBoldFont (class WideBoldFont)
	       This option specifies the font to be used  for  displaying  bold  wide  text.   By
	       default, it will attempt to use a font twice as wide as the font that will be used
	       to draw bold text.  If no  doublewidth  font  is  found,  it  will  improvise,  by
	       stretching the bold font.

       wideChars (class WideChars)
	       Specifies if xterm should respond to control sequences that process 16-bit charac-
	       ters.  The default is ``false.''

       wideFont (class WideFont)
	       This option specifies the font to be used for displaying wide text.   By  default,
	       it  will attempt to use a font twice as wide as the font that will be used to draw
	       normal text.  If no doublewidth font is found, it will  improvise,  by  stretching
	       the normal font.

       ximFont (class XimFont)
	       This option specifies the font to be used for displaying the preedit string in the
	       "OverTheSpot" input method.

	       In "OverTheSpot" preedit type, the preedit (preconversion) string is displayed  at
	       the  position of the cursor.  It is the XIM server's responsibility to display the
	       preedit string.	The XIM client must inform the XIM server of the cursor position.
	       For best results, the preedit string must be displayed with a proper font.  There-
	       fore, xterm informs the XIM server of the proper font.  The font is be supplied by
	       a  "fontset",  whose default value is "*".  This matches every font, the X library
	       automatically chooses fonts with proper charsets.  The ximFont  resource  is  pro-
	       vided to override this default font setting.

   Tek4014 Widget Resources
       The  following  resources  are  specified  as  part of the tek4014 widget (class Tek4014).
       These are specified by patterns such as "XTerm.tek4014.NAME":

       font2 (class Font)
	       Specifies font number 2 to use in the Tektronix window.

       font3 (class Font)
	       Specifies font number 3 to use in the Tektronix window.

       fontLarge (class Font)
	       Specifies the large font to use in the Tektronix window.

       fontSmall (class Font)
	       Specifies the small font to use in the Tektronix window.

       ginTerminator (class GinTerminator)
	       Specifies what character(s) should follow a GIN report or status report.  The pos-
	       sibilities  are ``none,'' which sends no terminating characters, ``CRonly,'' which
	       sends CR, and ``CR&EOT,'' which sends both CR and EOT.  The default is ``none.''

       height (class Height)
	       Specifies the height of the Tektronix window in pixels.

       initialFont (class InitialFont)
	       Specifies which of the four Tektronix fonts to use initially.  Values are the same
	       as for the set-tek-text action.	The default is ``large.''

       width (class Width)
	       Specifies the width of the Tektronix window in pixels.

   Menu Resources
       The  resources that may be specified for the various menus are described in the documenta-
       tion for the Athena SimpleMenu widget.  The name and classes of the entries in each of the
       menus  are  listed below.  Resources named "lineN" where N is a number are separators with
       class SmeLine.

       The mainMenu has the following entries:

       toolbar (class SmeBSB)
	       This entry invokes the set-toolbar(toggle) action.

   Scrollbar Resources
       The following resources are useful when specified for the Athena Scrollbar widget:

       thickness (class Thickness)
	       Specifies the width in pixels of the scrollbar.

       background (class Background)
	       Specifies the color to use for the background of the scrollbar.

       foreground (class Foreground)
	       Specifies the color to use for the foreground of the scrollbar.	The ``thumb''  of
	       the  scrollbar  is a simple checkerboard pattern alternating pixels for foreground
	       and background color.

POINTER USAGE
       Once the VT102 window is created, xterm allows you to select text and copy it  within  the
       same or other windows.

   SELECTION
       The  selection  functions are invoked when the pointer buttons are used with no modifiers,
       and when they are used with the ``shift'' key.  The assignment of the functions	described
       below to keys and buttons may be changed through the resource database; see ACTIONS below.

       Pointer button one (usually left) is used to save text into the cut buffer.  Move the cur-
       sor to beginning of the text, and then hold the button down while moving the cursor to the
       end of the region and releasing the button.  The selected text is highlighted and is saved
       in the global cut buffer and made the PRIMARY selection when the button is released.  Nor-
       mally (but see the discussion of on2Clicks, etc):

	      -  Double-clicking selects by words.

	      -  Triple-clicking selects by lines.

	      -  Quadruple-clicking goes back to characters, etc.

       Multiple-click  is determined by the time from button up to button down, so you can change
       the selection unit in the middle of a selection.  Logical words and lines selected by dou-
       ble- or triple-clicking may wrap across more than one screen line if lines were wrapped by
       xterm itself rather than by the application running in  the  window.   If  the  key/button
       bindings  specify  that	an  X selection is to be made, xterm will leave the selected text
       highlighted for as long as it is the selection owner.

       Pointer button two (usually middle) `types' (pastes) the text from the PRIMARY  selection,
       if any, otherwise from the cut buffer, inserting it as keyboard input.

       Pointer button three (usually right) extends the current selection.  (Without loss of gen-
       erality, you can swap ``right'' and ``left'' everywhere in the rest  of	this  paragraph.)
       If  pressed while closer to the right edge of the selection than the left, it extends/con-
       tracts the right edge of the selection.	If you contract the selection past the left  edge
       of  the	selection,  xterm  assumes  you really meant the left edge, restores the original
       selection, then extends/contracts the left edge of the selection.  Extension starts in the
       selection  unit mode that the last selection or extension was performed in; you can multi-
       ple-click to cycle through them.

       By cutting and pasting pieces of text without trailing new lines, you can take  text  from
       several	places in different windows and form a command to the shell, for example, or take
       output from a program and insert it into your favorite  editor.	 Since	cut  buffers  are
       globally  shared  among different applications, you may regard each as a `file' whose con-
       tents you know.	The terminal emulator and other text programs should be treating it as if
       it were a text file, i.e., the text is delimited by new lines.

   SCROLLING
       The scroll region displays the position and amount of text currently showing in the window
       (highlighted) relative to the amount of text actually saved.  As more text is saved (up to
       the maximum), the size of the highlighted area decreases.

       Clicking  button  one with the pointer in the scroll region moves the adjacent line to the
       top of the display window.

       Clicking button three moves the top line of the display window down to the  pointer  posi-
       tion.

       Clicking  button two moves the display to a position in the saved text that corresponds to
       the pointer's position in the scrollbar.

   TEKTRONIX POINTER
       Unlike the VT102 window, the Tektronix window does not allow the copying of text.  It does
       allow  Tektronix  GIN  mode,  and  in  this mode the cursor will change from an arrow to a
       cross.  Pressing any key will send that key and the current coordinate of the  cross  cur-
       sor.   Pressing	button	one,  two,  or	three  will return the letters `l', `m', and `r',
       respectively.  If the `shift' key is pressed when a pointer button is pressed, the  corre-
       sponding  upper case letter is sent.  To distinguish a pointer button from a key, the high
       bit of the character is set (but this is bit is normally stripped unless the terminal mode
       is RAW; see tty(4) for details).

MENUS
       Xterm  has  four  menus, named mainMenu, vtMenu, fontMenu, and tekMenu.	Each menu pops up
       under the correct combinations of key and button presses.  Each menu is divided into  sec-
       tions,  separated by a horizontal line.	Some menu entries correspond to modes that can be
       altered.  A check mark appears next to a mode that is currently active.	Selecting one  of
       these  modes  toggles  its state.  Other menu entries are commands; selecting one of these
       performs the indicated function.

       All of the menu entries correspond to X actions.  In the list below,  the  menu	label  is
       shown followed by the action's name in parenthesis.

   Main Options
       The  xterm mainMenu pops up when the ``control'' key and pointer button one are pressed in
       a window.  This menu contains items that apply to both the VT102  and  Tektronix  windows.
       There are several sections:

       Commands for managing X events:

	      Toolbar
		     Clicking on the "Toolbar" menu entry hides the toolbar if it is visible, and
		     shows it if it is not.

	      Secure Keyboard (securekbd)
		     The Secure Keyboard mode is helpful when typing in passwords or other sensi-
		     tive data in an unsecure environment; see SECURITY below (but read the limi-
		     tations carefully).

	      Allow SendEvents (allowsends)
		     Specifies whether or not synthetic key and button events generated using the
		     X	protocol SendEvent request should be interpreted or discarded.	This cor-
		     responds to the allowSendEvents resource.

	      Redraw Window (redraw)
		     Forces the X display to repaint; useful in some environments.

       Commands for capturing output:

	      Log to File (logging)
		     Captures text sent to the screen in a logfile, as in the -l logging option.

	      Print Window (print)
		     Sends the text of the current window to the program given in the printerCom-
		     mand resource.

	      Redirect to Printer (print-redir)
		     This  sets  the  printerControlMode to 0 or 2.  You can use this to turn the
		     printer on as if an application had sent the appropriate  control	sequence.
		     It  is  also useful for switching the printer off if an application turns it
		     on without resetting the print control mode.

       Modes for setting keyboard style:

	      8-Bit Controls (8-bit-control)
		     Enabled for VT220 emulation, this controls whether  xterm	will  send  8-bit
		     control  sequences rather than using 7-bit (ASCII) controls, e.g., sending a
		     byte in the range 128-159 rather than the escape  character  followed  by	a
		     second byte.  Xterm always interprets both 8-bit and 7-bit control sequences
		     (see the document Xterm Control Sequences).  This corresponds to the  eight-
		     BitControl resource.

	      Backarrow Key (BS/DEL) (backarrow key)
		     Modifies  the  behavior  of  the  backarrow key, making it transmit either a
		     backspace(8) or delete(127) character.  This corresponds  to  the  backar-
		     rowKey resource.

	      Alt/NumLock Modifiers (num-lock)
		     Controls  the treatment of Alt- and NumLock-key modifiers.  This corresponds
		     to the numLock resource.

	      Meta Sends Escape (meta-esc)
		     Controls whether Meta keys are converted into a two-character sequence  with
		     the  character  itself  preceded  by ESC.	This corresponds to the metaSend-
		     sEscape resource.

	      Delete is DEL (delete-is-del)
		     Controls whether the Delete key on the editing keypad should send DEL(127)
		     or  the  VT220-style  Remove  escape  sequence.   This  corresponds  to  the
		     deleteIsDEL resource.

	      Old Function-Keys (oldFunctionKeys)

	      HP Function-Keys (hpFunctionKeys)

	      SCO Function-Keys (scoFunctionKeys)

	      Sun Function-Keys (sunFunctionKeys)

	      VT220 Keyboard (sunKeyboard)
		     These act as a radio-button, selecting one style for  the	keyboard  layout.
		     It  corresponds to more than one resource setting: sunKeyboard, sunFunction-
		     Keys, scoFunctionKeys and hpFunctionKeys ."

       Commands for process signalling:

	      Send STOP Signal (suspend)

	      Send CONT Signal (continue)

	      Send INT Signal (interrupt)

	      Send HUP Signal (hangup)

	      Send TERM Signal (terminate)

	      Send KILL Signal (kill)
		     These send the SIGTSTP, SIGCONT, SIGINT, SIGHUP, SIGTERM and SIGKILL signals
		     respectively,  to the process group of the process running under xterm (usu-
		     ally the shell).  The SIGCONT function is especially useful if the user  has
		     accidentally typed CTRL-Z, suspending the process.

	      Quit (quit)
		     Stop processing X events except to support the -hold option, and then send a
		     SIGHUP signal to the the process group of the process  running  under  xterm
		     (usually the shell).

   VT Options
       The  vtMenu  sets  various  modes in the VT102 emulation, and is popped up when the ``con-
       trol'' key and pointer button two are pressed in the VT102 window.

       VT102/VT220 Modes:

	      Enable Scrollbar (scrollbar)
		     Enable (or disable) the scrollbar.  This corresponds to the -sb  option  and
		     the scrollBar resource.

	      Enable Jump Scroll (jumpscroll)
		     Enable  (or  disable) jump scrolling.  This corresponds to the -j option and
		     the jumpScroll resource.

	      Enable Reverse Video (reversevideo)
		     Enable (or disable) reverse-video.  This corresponds to the -rv  option  and
		     the reverseVideo resource.

	      Enable Auto Wraparound (autowrap)
		     Enable (or disable) auto-wraparound.  This corresponds to the -aw option and
		     the autoWrap resource.

	      Enable Reverse Wraparound (reversewrap)
		     Enable (or disable) reverse wraparound.  This corresponds to the -rw  option
		     and the reverseWrap resource.

	      Enable Auto Linefeed (autolinefeed)
		     Enable  (or  disable)  auto-linefeed.  This is the VT102 NEL function, which
		     causes the emulator to emit a linefeed after each carriage return.  There is
		     no corresponding command-line option or resource setting.

	      Enable Application Cursor Keys (appcursor)
		     Enable  (or  disable)  application  cursor  keys.	 This  corresponds to the
		     appcursorDefault resource.  There is no corresponding command-line option.

	      Enable Application Keypad (appkeypad)
		     Enable (or disable) application keypad keys.  This corresponds to	the  app-
		     keypadDefault resource.  There is no corresponding command-line option.

	      Scroll to Bottom on Key Press (scrollkey)
		     Enable  (or  disable)  scrolling  to the bottom of the scrolling region on a
		     keypress.	This corresponds to the -sk option and the scrollKey resource.

	      Scroll to Bottom on Tty Output (scrollttyoutput)
		     Enable (or disable) scrolling to the bottom of the scrolling region on  out-
		     put  to the terminal.  This corresponds to the -si option and the scrollTty-
		     Output resource.

	      Allow 80/132 Column Switching (allow132)
		     Enable (or disable) switching between 80 and 132 columns.	This  corresponds
		     to the -132 option and the c132 resource.

	      Keep Selection (keepSelection)
		     Tell  xterm  whether  to disown the selection when it stops highlighting it,
		     e.g., when an application modifies the display so that it no longer  matches
		     the  text which has been highlighted.  As long as xterm continues to own the
		     selection, it can provide	the  corresponding  text  to  other  clients  via
		     cut/paste.   This	corresponds  to  the keepSelection resource.  There is no
		     corresponding command-line option.

	      Select to Clipboard (selectToClipboard)
		     Tell xterm whether to use the PRIMARY or CLIPBOARD for SELECT tokens in  the
		     translations  resource which maps keyboard and mouse actions to select/paste
		     actions.  This corresponds to the selectToClipboard resource.  There  is  no
		     corresponding command-line option.

	      Enable Visual Bell (visualbell)
		     Enable  (or  disable)  visible  bell  (i.e., flashing) instead of an audible
		     bell.  This corresponds to the -vb option and the visualBell resource.

	      Enable Bell Urgency (bellIsUrgent)
		     Enable (or disable) Urgency window manager hint when Control-G is	received.
		     This corresponds to the bellIsUrgent resource.

	      Enable Pop on Bell (poponbell)
		     Enable  (or disable) raising of the window when Control-G is received.  This
		     corresponds to the -pop option and the popOnBell resource.

	      Enable Blinking Cursor (cursorblink)
		     Enable (or disable) the blinking-cursor feature.  This  corresponds  to  the
		     -bc  option  and the cursorBlink resource.  There is also an escape sequence
		     (see the document Xterm Control Sequences).  The menu entry and  the  escape
		     sequence  states  are XOR'd: if both are enabled, the cursor will not blink,
		     if only one is enabled, the cursor will blink.

	      Enable Alternate Screen Switching (titeInhibit)
		     Enable (or disable) switching between  the  normal  and  alternate  screens.
		     This  corresponds	to  the  titeInhibit resource.	There is no corresponding
		     command-line option.

	      Enable Active Icon (activeicon)
		     Enable (or disable) the active-icon feature.  This corresponds  to  the  -ai
		     option and the activeIcon resource.

       VT102/VT220 Commands:

	      Do Soft Reset (softreset)
		     Reset scroll regions.  This can be convenient when some program has left the
		     scroll regions set incorrectly (often a problem when using VMS or	TOPS-20).
		     This corresponds to the VT220 DECSTR control sequence.

	      Do Full Reset (hardreset)
		     The  full	reset entry will clear the screen, reset tabs to every eight col-
		     umns, and reset the terminal modes (such as wrap and smooth scroll) to their
		     initial  states  just  after  xterm has finished processing the command line
		     options.  This corresponds to the VT102 RIS control  sequence,  with  a  few
		     obvious  differences.   For  example,  your session is not disconnected as a
		     real VT102 would do.

	      Reset and Clear Saved Lines (clearsavedlines)
		     Perform a full reset, and also clear the saved lines.

       Commands for setting the current screen:

	      Show Tek Window (tekshow)
		     When enabled, pops the Tektronix 4014 window up (makes  it  visible).   When
		     disabled, hides the Tektronix 4014 window.

	      Switch to Tek Mode (tekmode)
		     When  enabled,  pops the Tektronix 4014 window up if it is not already visi-
		     ble, and switches the input stream to that window.  When disabled, hides the
		     Tektronix 4014 window and switches input back to the VTxxx window.

	      Hide VT Window (vthide)
		     When  enabled, hides the VTxxx window, shows the Tektronix 4014 window if it
		     was not already visible and switches the input stream to that window.   When
		     disabled, shows the VTxxx window, and switches the input stream to that win-
		     dow.

	      Show Alternate Screen (altscreen)
		     When enabled, shows the alternate screen.	When disabled, shows  the  normal
		     screen.   Note  that  the	normal screen may have saved lines; the alternate
		     screen does not.

   VT Fonts
       The fontMenu pops up when when the ``control'' key and pointer button three are pressed in
       a  window.   It	sets  the  font used in the VT102 window, or modifies the way the font is
       specified or displayed.	There are several sections.

       The first section allows you to select the font from a set of alternatives:

	      Default (fontdefault)
		     Set the font to the default, i.e., that given by the *VT100.font resource.

	      Unreadable (font1)
		     Set the font to that given by the *VT100.font1 resource.

	      Tiny (font2)
		     Set the font to that given by the *VT100.font2 resource.

	      Small (font3)
		     Set the font to that given by the *VT100.font3 resource.

	      Medium (font4)
		     Set the font to that given by the *VT100.font4 resource.

	      Large (font5)
		     Set the font to that given by the *VT100.font5 resource.

	      Huge (font6)
		     Set the font to that given by the *VT100.font6 resource.

	      Escape Sequence
		     This allows you to set the font  last  specified  by  the	Set  Font  escape
		     sequence (see the document Xterm Control Sequences).

	      Selection (fontsel)
		     This  allows  you	to set the font specified the current selection as a font
		     name (if the PRIMARY selection is owned).

       The second section allows you to modify the way it is displayed:

	      Line-Drawing Characters (font-linedrawing)
		     When set, tells xterm to draw its own line-drawing characters.  Otherwise it
		     relies on the font containing these.  Compare to the forceBoxChars resource.

	      Doublesized Characters (font-doublesize)
		     When  set,  xterm	may ask the font server to produce scaled versions of the
		     normal font, for VT102 double-size characters.

       The third section allows you to modify the way it is specified:

	      TrueType Fonts (render-font)
		     If the renderFont and corresponding resources were set, this  is  a  further
		     control  whether  xterm  will actually use the Xft library calls to obtain a
		     font.

	      UTF-8 (utf8-mode)
		     This controls whether xterm uses UTF-8 encoding of input/output.  It is use-
		     ful  for  temporarily  switching  xterm  to display text from an application
		     which does not follow the locale settings.

       The fourth section allows you to enable or disable special operations which  can  be  con-
       trolled by writing escape sequences to the terminal.  These are disabled if the SendEvents
       feature is enabled:

	      Allow Font Ops (allow-font-ops)
		     This corresponds to the allowFontOps resource.  Enable  or  disable  control
		     sequences that set/query the font.

	      Allow Tcap Ops (allow-tcap-ops)
		     Enable  or disable control sequences that query the terminal's notion of its
		     function-key strings, as termcap or terminfo capabilities.  This corresponds
		     to the allowTcapOps resource.

	      Allow Title Ops (allow-title-ops)
		     Enable  or  disable  control  sequences that modify the window title or icon
		     name.  This corresponds to the allowTitleOps resource.

	      Allow Window Ops (allow-window-ops)
		     Enable or disable extended window control sequences  (as  used  in  dtterm).
		     This corresponds to the allowWindowOps resource.

   TEK Options
       The  tekMenu  sets  various  modes  in  the Tektronix emulation, and is popped up when the
       ``control'' key and pointer button two are pressed in the Tektronix window.   The  current
       font size is checked in the modes section of the menu.

	      Large Characters (tektextlarge)

	      #2 Size Characters (tektext2)

	      #3 Size Characters (tektext3)

	      Small Characters (tektextsmall)

       Commands:

	      PAGE (tekpage)
		     Clear the Tektronix window.

	      RESET (tekreset)

	      COPY (tekcopy)

       Windows:

	      Show VT Window (vtshow)

	      Switch to VT Mode (vtmode)

	      Hide Tek Window (tekhide)

SECURITY
       X  environments	differ in their security consciousness.  Most servers, run under xdm, are
       capable of using a ``magic cookie'' authorization scheme that  can  provide  a  reasonable
       level of security for many people.  If your server is only using a host-based mechanism to
       control access to the server (see xhost(1)), then if you enable	access	for  a	host  and
       other users are also permitted to run clients on that same host, it is possible that some-
       one can run an application which uses the basic services of the X  protocol  to	snoop  on
       your  activities,  potentially  capturing  a transcript of everything you type at the key-
       board.  Any process which has access to your X display can manipulate it in ways that  you
       might  not anticipate, even redirecting your keyboard to itself and sending events to your
       application's windows.  This is true even with the ``magic cookie'' authorization  scheme.
       While  the  allowSendEvents  provides some protection against rogue applications tampering
       with your programs, guarding against a snooper is harder.

       The possibility of an application spying on your keystrokes is of particular concern  when
       you want to type in a password or other sensitive data.	The best solution to this problem
       is to use a better authorization mechanism than is provided by  X.   Given  all	of  these
       caveats, a simple mechanism exists for protecting keyboard input in xterm.

       The  xterm  menu  (see  MENUS above) contains a Secure Keyboard entry which, when enabled,
       attempts to ensure that all keyboard input is directed only to xterm (using  the  GrabKey-
       board  protocol request).  When an application prompts you for a password (or other sensi-
       tive data), you can enable Secure Keyboard using the menu, type in the data, and then dis-
       able  Secure  Keyboard  using  the menu again.  This ensures that you know which window is
       accepting your keystrokes.  It cannot ensure that there are no processes which have access
       to your X display that might be observing the keystrokes as well.

       Only  one  X  client at a time can grab the keyboard, so when you attempt to enable Secure
       Keyboard it may fail.  In this case, the bell will sound.  If  the  Secure  Keyboard  suc-
       ceeds,  the  foreground	and  background  colors will be exchanged (as if you selected the
       Reverse Video entry in the Modes menu); they will be exchanged again when you exit  secure
       mode.   If the colors do not switch, then you should be very suspicious that you are being
       spoofed.  If the application you are running displays a prompt before asking for the pass-
       word, it is safest to enter secure mode before the prompt gets displayed, and to make sure
       that the prompt gets displayed correctly (in the new colors), to minimize the  probability
       of spoofing.  You can also bring up the menu again and make sure that a check mark appears
       next to the entry.

       Secure Keyboard mode will be disabled automatically if your xterm window becomes iconified
       (or  otherwise  unmapped),  or if you start up a reparenting window manager (that places a
       title bar or other decoration around the window) while in Secure Keyboard mode.	(This  is
       a  feature  of the X protocol not easily overcome.)  When this happens, the foreground and
       background colors will be switched back and the bell will sound in warning.

CHARACTER CLASSES
       Clicking the left pointer button twice in rapid succession  (double-clicking)  causes  all
       characters of the same class (e.g., letters, white space, punctuation) to be selected as a
       ``word''.  Since different people have different preferences for what should  be  selected
       (for  example, should filenames be selected as a whole or only the separate subnames), the
       default mapping can be overridden through the  use  of  the  charClass  (class  CharClass)
       resource.

       This  resource is a series of comma-separated of range:value pairs.  The range is either a
       single number or low-high in the range of 0 to 65535, corresponding to the  code  for  the
       character  or  characters  to  be set.  The value is arbitrary, although the default table
       uses the character number of the first character occurring in the set.  When not in  UTF-8
       mode, only the first 256 bytes of this table will be used.

       The default table starts as follows -

	   static int charClass[256] = {
	   /* NUL  SOH	STX  ETX  EOT  ENQ  ACK  BEL */
	       32,   1,   1,   1,   1,	 1,   1,   1,

       For  example,  the  string  ``33:48,37:48,45-47:48,38:48''  indicates that the exclamation
       mark, percent sign, dash, period, slash, and ampersand characters should  be  treated  the
       same  way  as  characters  and numbers.	This is useful for cutting and pasting electronic
       mailing addresses and filenames.

ACTIONS
       It is possible to rebind keys (or sequences of keys) to arbitrary strings  for  input,  by
       changing the translations resources for the vt100 or tek4014 widgets.  Changing the trans-
       lations resource for events other than key and button events is	not  expected,	and  will
       cause unpredictable behavior.  The following actions are provided for use within the vt100
       or tek4014 translations resources:

       allow-font-ops(on/off/toggle)
	       This action set or toggles the allowFontOps resource and is also  invoked  by  the
	       allow-font-ops entry in fontMenu.

       allow-send-events(on/off/toggle)
	       This action set or toggles the allowSendEvents resource and is also invoked by the
	       allowsends entry in mainMenu.

       allow-tcap-ops(on/off/toggle)
	       This action set or toggles the allowTcapOps resource and is also  invoked  by  the
	       allow-tcap-ops entry in fontMenu.

       allow-title-ops(on/off/toggle)
	       This  action  set or toggles the allowTitleOps resource and is also invoked by the
	       allow-title-ops entry in fontMenu.

       allow-window-ops(on/off/toggle)
	       This action set or toggles the allowWindowOps resource and is also invoked by  the
	       allow-window-ops entry in fontMenu.

       alt-sends-escape()
	       This action toggles the state of the eightBitInput resource.

       bell([percent])
	       This action rings the keyboard bell at the specified percentage above or below the
	       base volume.

       clear-saved-lines()
	       This action does hard-reset() (see below) and also clears  the  history	of  lines
	       saved  off  the	top  of  the screen.  It is also invoked from the clearsavedlines
	       entry in vtMenu.  The effect is	identical  to  a  hardware  reset  (RIS)  control
	       sequence.

       create-menu(m/v/f/t)
	       This  action creates one of the menus used by xterm, if it has not been previously
	       created.  The parameter values are the menu  names:  mainMenu,  vtMenu,	fontMenu,
	       tekMenu, respectively.

       dabbrev-expand()
	       Expands	the  word  before cursor by searching in the preceding text on the screen
	       and in the scrollback buffer for words starting with that abbreviation.	Repeating
	       dabbrev-expand()  several  times in sequence searches for an alternative expansion
	       by looking farther back.  Lack of more matches is signaled by a beep().	 Attempts
	       to  expand  an empty word (i.e., when cursor is preceded by a space) yield succes-
	       sively all previous words.  Consecutive identical  expansions  are  ignored.   The
	       word  here  is  defined	as a sequence of non-whitespace characters.  This feature
	       partially emulates the behavior	of  `dynamic  abbreviation'  expansion	in  Emacs
	       (bound there to M-/).  Here is a resource setting for xterm which will do the same
	       thing:

		   *VT100*translations:    #override \n\
			   Meta <KeyPress> /:dabbrev-expand()

       deiconify()
	       Changes the window state back to normal, if it was iconified.

       delete-is-del()
	       This action toggles the state of the deleteIsDEL resource.

       dired-button()
	       Handles a button event (other than press and release) by echoing the event's posi-
	       tion (i.e., character line and column) in the following format:

		       ^X ESC G <line+' '> <col+' '>

       iconify()
	       Iconifies the window.

       hard-reset()
	       This  action  resets  the scrolling region, tabs, window size, and cursor keys and
	       clears the screen.  It is also invoked from the hardreset entry in vtMenu.

       ignore()
	       This action ignores the event but  checks  for  special	pointer  position  escape
	       sequences.

       insert()
	       This  action  inserts  the  character  or  string associated with the key that was
	       pressed.

       insert-eight-bit()
	       This action inserts an eight-bit (Meta) version of the character or string associ-
	       ated with the key that was pressed.  This only applies to single-byte values.  The
	       exact action depends on the value of the  metaSendsEscape  and  the  eightBitInput
	       resources.  The metaSendsEscape resource is tested first.

	       The  term  "eight-bit" is misleading: xterm checks if the key's value is less than
	       128.  If so, xterm adds 128 to the value, setting its eighth bit.  Otherwise xterm
	       sends  an  ESC byte before the key.  In other applications' documentation, that is
	       referred to as a "meta key".

       insert-selection(sourcename [, ...])
	       This action inserts the string found in the selection or  cutbuffer  indicated  by
	       sourcename.   Sources  are  checked in the order given (case is significant) until
	       one is found.  Commonly-used selections include:  PRIMARY,  SECONDARY,  and  CLIP-
	       BOARD.  Cut buffers are typically named CUT_BUFFER0 through CUT_BUFFER7.

       insert-seven-bit()
	       This  action is a synonym for insert() The term "seven-bit" is misleading: it only
	       implies that xterm does not try to add 128 to the key's value as in  insert-eight-
	       bit().

       interpret(control-sequence)
	       Interpret  the  given  control  sequence  locally, i.e., without passing it to the
	       host.  This works by inserting the control sequence at the front of the input buf-
	       fer.   Use "\" to escape octal digits in the string.  Xt does not allow you to put
	       a null character (i.e., "\000") in the string.

       keymap(name)
	       This action dynamically defines a new translation table	whose  resource  name  is
	       name  with  the	suffix	Keymap (case is significant).  The name None restores the
	       original translation table.

       larger-vt-font()
	       Set the font to the next larger one, based on the font dimensions.  See also  set-
	       vt-font().

       load-vt-fonts(name[,class])
	       Load  fontnames	from  the  given  subresource  name and class.	That is, load the
	       "*VT100.name.font", resource as "*VT100.font" etc.  If no name is given, the orig-
	       inal set of fontnames is restored.

	       Unlike  set-vt-font(),  this  does  not affect the escape- and select-fonts, since
	       those are not based on resource values.	It does affect the  fonts  loosely  orga-
	       nized under the ``Default'' menu entry: font, boldFont, wideFont and wideBoldFont.

       print-redir()
	       This action toggles the printerControlMode between 0  and  2.   The  corresponding
	       popup  menu  entry is useful for switching the printer off if you happen to change
	       your mind after deciding to print random binary files on the terminal.

       quit()  This action sends a SIGHUP to the subprogram and exits.	It is also invoked by the
	       quit entry in mainMenu.

	       Restores the window to the size before it was last maximized.

       scroll-back(count [,units [,mouse] ])
	       This action scrolls the text window backward so	that  text  that  had  previously
	       scrolled off the top of the screen is now visible.

	       The  count  argument  indicates	the number of units (which may be page, halfpage,
	       pixel, or line) by which to scroll.

	       An adjustment can be specified for these values by appending a  "+"  or	"-"  sign
	       followed by a number, e.g., page-2 to specify 2 lines less than a page.

	       If  the third parameter mouse is given, the action is ignored when mouse reporting
	       is enabled.

	       This  action  sends the signal named by signame to the xterm subprocess (the shell
	       or program specified with the -e command line option) and is also invoked  by  the
	       suspend,  continue,  interrupt,	hangup,  terminate, and kill entries in mainMenu.
	       Allowable signal names are (case is not significant): tstp (if  supported  by  the
	       operating  system),  suspend  (same  as tstp), cont (if supported by the operating
	       system), int, hup, term, quit, alrm, alarm (same as alrm) and kill.

	       entry in vtMenu.

       set-vt-font(d/1/2/3/4/5/6/e/s [,normalfont [, boldfont]])
	       This action sets the font or fonts currently being used in the VT102 window.   The
	       first argument is a single character that specifies the font to be used:

	       d or D indicate the default font (the font initially used when xterm was started),

	       1 through 6 indicate the fonts specified by the font1 through font6 resources,

	       e  or E indicate the normal and bold fonts that have been set through escape codes
		      (or specified as the second and third action arguments, respectively), and

	       s or S indicate the font selection (as made by programs such as xfontsel(1)) indi-
		      cated by the second action argument.

	       If  xterm  is  configured  to  support wide characters, an additional two optional
	       parameters are recognized for the e argument: wide font and wide bold font.

       smaller-vt-font()
	       Set the font to the next smaller one, based on the font dimensions.  See also set-
	       vt-font().

       soft-reset()
	       This  action  resets  the  scrolling region and is also invoked from the softreset
	       entry in vtMenu.  The effect  is  identical  to	a  soft  reset	(DECSTR)  control
	       sequence.

       spawn-new-terminal(params)
	       Spawn  a new xterm process.  This is available on systems which have a modern ver-
	       sion of the process filesystem, e.g., "/proc", which xterm can read.

	       Use the "cwd" process entry, e.g., /proc/12345/cwd to obtain the working directory
	       of the process which is running in the current xterm.

	       On  systems which have the "exe" process entry, e.g., /proc/12345/exe, use this to
	       obtain the actual executable.  Otherwise, use the $PATH variable to find xterm.

	       If parameters are given in the action, pass them to the new xterm process.

       start-extend()
	       This action is similar to select-start except that the selection  is  extended  to
	       the current pointer location.

       start-cursor-extend()
	       This  action  is similar to select-extend except that the selection is extended to
	       the current text cursor position.

       string(string)
	       This action inserts the specified text string as if it had been typed.	Quotation
	       is necessary if the string contains whitespace or non-alphanumeric characters.  If
	       the string argument begins with the characters ``0x'', it is interpreted as a  hex
	       character constant.

       tek-copy()
	       This  action  copies the escape codes used to generate the current window contents
	       to a file in the current directory beginning with  the  name  COPY.   It  is  also
	       invoked from the tekcopy entry in tekMenu.

       tek-page()
	       This  action  clears the Tektronix window and is also invoked by the tekpage entry
	       in tekMenu.

       tek-reset()
	       This action resets the Tektronix window and is also invoked by the tekreset  entry
	       in tekMenu.

       vi-button()
	       Handles	a  button  event  (other  than	press  and  release) by echoing a control
	       sequence computed from the event's line number in the screen relative to the  cur-
	       rent line:

		       ESC ^P
	       or
		       ESC ^N

	       according to whether the event is before, or after the current line, respectively.
	       The ^N (or ^P) is repeated once for each line that the event differs from the cur-
	       rent  line.   The control sequence is omitted altogether if the button event is on
	       the current line.

       visual-bell()
	       This action flashes the window quickly.

       The Tektronix window also has the following action:

       gin-press(l/L/m/M/r/R)
	       This action sends the indicated graphics input code.

       The default bindings in the VT102 window use the SELECT token, which is set by the select-
       ToClipboard resource:

       The default bindings for the scrollbar widget are separate from the VT100 widget:

				 <Btn5Down>: StartScroll(Forward) \n\
				 <Btn1Down>: StartScroll(Forward) \n\
				 <Btn2Down>: StartScroll(Continuous) MoveThumb() NotifyThumb() \n\
				 <Btn3Down>: StartScroll(Backward) \n\
				 <Btn4Down>: StartScroll(Backward) \n\
				 <Btn2Motion>: MoveThumb() NotifyThumb() \n\
				 <BtnUp>:    NotifyScroll(Proportional) EndScroll()

       The default bindings in the Tektronix window are:

			    ~Meta<KeyPress>: insert-seven-bit() \n\
			     Meta<KeyPress>: insert-eight-bit() \n\
			   !Ctrl <Btn1Down>: popup-menu(mainMenu) \n\
		      !Lock Ctrl <Btn1Down>: popup-menu(mainMenu) \n\

		      Shift ~Meta<Btn3Down>: gin-press(R) \n\
			    ~Meta<Btn3Down>: gin-press(r)

       Here is an example which uses shifted select/paste to copy to the clipboard, and unshifted
       select/paste for the primary selection.	In each case, a (different) cut buffer is also	a
       target or source of the select/paste operation.	It is important to remember however, that
       cut buffers store data in ISO-8859-1 encoding, while selections can store data in a  vari-
       ety  of formats and encodings.  While xterm owns the selection, it highlights it.  When it
       loses the selection, it removes the corresponding highlight.  But you can still paste from
       the corresponding cut buffer.

	   *VT100*translations:    #override \n\
	       ~Shift~Ctrl<Btn2Up>: insert-selection(PRIMARY, CUT_BUFFER0) \n\
	       Shift~Ctrl<Btn2Up>:  insert-selection(CLIPBOARD, CUT_BUFFER1) \n\
	       ~Shift<BtnUp>:	    select-end(PRIMARY, CUT_BUFFER0) \n\
	       Shift<BtnUp>:	    select-end(CLIPBOARD, CUT_BUFFER1)

       Below is a sample how of the keymap() action is used to add special keys for entering com-
       monly-typed works:

	   *VT100.Translations: #override <Key>F13: keymap(dbx)
	   *VT100.dbxKeymap.translations: \
		<Key>F14: keymap(None) \n\
		<Key>F17: string("next") string(0x0d) \n\
		<Key>F18: string("step") string(0x0d) \n\
		<Key>F19: string("continue") string(0x0d) \n\
		<Key>F20: string("print ") insert-selection(PRIMARY, CUT_BUFFER0)

       Some people prefer using the left pointer button for dragging the scrollbar  thumb.   That
       can be setup by altering the translations resource, e.g.,

	   *VT100.scrollbar.translations:#override \n\
		<Btn5Down>:StartScroll(Forward) \n\
		<Btn1Down>:StartScroll(Continuous) MoveThumb() NotifyThumb() \n\
		<Btn4Down>:StartScroll(Backward) \n\
		<Btn1Motion>:MoveThumb() NotifyThumb() \n\
		<BtnUp>:  NotifyScroll(Proportional) EndScroll()

CONTROL SEQUENCES AND KEYBOARD
       The  Xterm Control Sequences document lists the control sequences which an application can
       send xterm to make it perform various operations.  Most of these operations are	standard-
       ized,  from either the DEC or Tektronix terminals, or from more widely used standards such
       as ISO-6429.

ENVIRONMENT
       Xterm sets several environment variables:

       DISPLAY
	    is the display name, pointing to the X server (see DISPLAY NAMES in X()).

       TERM is set according to the termcap (or terminfo) entry which it is using as a reference.

       WINDOWID
	    is set to the X window id number of the xterm window.

       XTERM_LOCALE
	    shows the locale which was used by	xterm  on  startup.   Some  shell  initialization
	    scripts may set a different locale.

       XTERM_SHELL
	    is set to the pathname of the program which is invoked.  Usually that is a shell pro-
	    gram, e.g., /bin/sh.  Since it is not necessarily a shell program however, it is dis-
	    tinct from ``SHELL''.

       XTERM_VERSION
	    is	set  to the string displayed by the -version option.  That is normally an identi-
	    fier for the X Window libraries used to build xterm, followed by xterm's patch number
	    in	parenthesis.  The patch number is also part of the response to a Secondary Device
	    Attributes (DA) control sequence (see Xterm Control Sequences).

       Depending on your system configuration, xterm may also set the following:

       COLUMNS
	    the width of the xterm in characters (cf: "stty columns").

       HOME when xterm is configured to update utmp.

       LINES
	    the height of the xterm in characters (cf: "stty rows").

       LOGNAME
	    when xterm is configured to update utmp.

       SHELL
	    when xterm is configured to update utmp.  It is also set if  you  provide  the  shell
	    name as the optional parameter.

       TERMCAP
	    the contents of the termcap entry corresponding to $TERM, with lines and columns val-
	    ues substituted for the actual size window you have created.

       TERMINFO
	    may be defined to a nonstandard location in the configure script.

FILES
       The actual pathnames given may differ on your system.

       /etc/utmp
	    the system logfile, which records user logins.

       /etc/wtmp
	    the system logfile, which records user logins and logouts.

       /usr/local/lib/X11/app-defaults/XTerm
	    the xterm default application resources.

       /usr/local/lib/X11/app-defaults/XTerm-color
	    the xterm color application resources.  If your display supports color, use this
		      *customization: -color
	    in your  .Xdefaults  file  to  automatically  use  this  resource  file  rather  than
	    /usr/local/lib/X11/app-defaults/XTerm.   If  you  do not do this, xterm uses its com-
	    piled-in default resource settings for colors.

ERROR MESSAGES
       Most of the fatal error messages from xterm use the following format:
	      xterm: Error XXX, errno YYY: ZZZ
       The XXX codes (which are used by xterm as its exit-code) are listed below,  with  a  brief
       explanation.

       1    is used for miscellaneous errors, usually accompanied by a specific message,

BUGS
       Large  pastes do not work on some systems.  This is not a bug in xterm; it is a bug in the
       pseudo terminal driver of those systems.  xterm feeds large pastes to the pty only as fast
       as the pty will accept data, but some pty drivers do not return enough information to know
       if the write has succeeded.

       Many of the options are not resettable after xterm starts.

       This program still needs to be rewritten.  It should be split into very modular	sections,
       with  the  various emulators being completely separate widgets that do not know about each
       other.  Ideally, you'd like to be able to pick and choose emulator widgets and stick  them
       into a single control widget.

       There needs to be a dialog box to allow entry of the Tek COPY file name.
