       pico - simple text editor in the style of the Pine Composer

       pico [ options ] [ file ]

       Pico  is a simple, display-oriented text editor based on the Pine message system composer.
       As with Pine, commands are displayed at the bottom of the  screen,  and	context-sensitive
       help is provided.  As characters are typed they are immediately inserted into the text.

       Editing	commands are entered using control-key combinations.  As a work-around for commu-
       nications programs that swallow certain control characters, you can emulate a control  key
       by  pressing  ESCAPE  twice,  followed  by the desired control character, e.g. "ESC ESC c"
       would be equivalent to entering a ctrl-c.  The editor has five basic  features:	paragraph
       justification, searching, block cut/paste, a spelling checker, and a file browser.

       Paragraph  justification  (or filling) takes place in the paragraph that contains the cur-
       sor, or, if the cursor is between lines, in the paragraph immediately  below.   Paragraphs
       are  delimited by blank lines, or by lines beginning with a space or tab.  Unjustification
       can be done immediately after justification using the control-U key combination.

       String searches are not sensitive to case.  A search begins at the current cursor position
       and  wraps  around  the	end of the text.  The most recent search string is offered as the
       default in subsequent searches.

       Blocks of text can be moved, copied or deleted with creative use of the command	for  mark
       (ctrl-^),  delete  (ctrl-k)  and  undelete  (ctrl-u).  The delete command will remove text
       between the "mark" and the current cursor position, and place it in the "cut" buffer.  The
       undelete command effects a "paste" at the current cursor position.

       The  spell  checker  examines  all  words in the text.  It then offers, in turn, each mis-
       spelled word for correction while highlighting it in the text.  Spell checking can be can-
       celled  at  any	time.  Alternatively, pico will substitute for the default spell checking
       routine a routine defined by the SPELL  environment  variable.	The  replacement  routine
       should read standard input and write standard output.

       The  file  browser  is  offered	as  an	option in the "Read File" and "Write Out" command
       prompts.  It is intended to help in searching for specific files and navigating	directory
       hierarchies.   Filenames with sizes and names of directories in the current working direc-
       tory are presented for selection.  The current working directory is displayed on  the  top
       line of the display while the list of available commands takes up the bottom two.  Several
       basic file manipulation functions are supported:  file renaming, copying, and deletion.

       More specific help is available in pico's online help.

       +n     Causes pico to be started with the cursor located n lines into the file. (Note:  no
	      space between "+" sign and number)

       -a     Display all files including those beginning with a period (.).

       -b     Enable the option to Replace text matches found using the "Where is" command.

       -d     Rebind the "delete" key so the character the cursor is on is rubbed out rather than
	      the character to its left.

       -e     Enable file name completion.

       -f     Use function keys for commands.  This option supported only in conjunction with  UW
	      Enhanced NCSA telnet.

       -h     List valid command line options.

       -j     Enable  "Goto"  command  in  the	file browser.  This enables the command to permit
	      explicitly telling pilot which directory to visit.

       -g     Enable "Show Cursor" mode in file browser.  Cause cursor to  be  positioned  before
	      the current selection rather than placed at the lower left of the display.

       -k     Causes  "Cut Text" command to remove characters from the cursor position to the end
	      of the line rather than remove the entire line.

       -m     Enable mouse functionality.  This only works when pico is run from within an X Win-
	      dow System "xterm" window.

       -nn    The  -nn	option	enables  new  mail notification.  The n argument is optional, and
	      specifies how often, in seconds, your mailbox is checked for new mail.   For  exam-
	      ple,  -n60 causes pico to check for new mail once every minute.  The default inter-
	      val is 180 seconds, while the minimum allowed is 30. (Note: no  space  between  "n"
	      and the number)

       -o dir Sets  operating directory.  Only files within this directory are accessible.  Like-
	      wise, the file browser is limited to the specified directory subtree.

       -rn    Sets column used to limit the "Justify" command's right margin

       -s speller
	      Specify an alternate program spell to use when spell checking.

       -t     Enable "tool" mode.  Intended for when pico is used  as  the  editor  within  other
	      tools  (e.g.,  Elm,  Pnews).   Pico  will not prompt for save on exit, and will not
	      rename the buffer during the "Write Out" command.

       -v     View the file only, disallowing any editing.

	      Print Pico version and exit.

       -w     Disable word wrap (thus allow editing of long lines).

       -x     Disable keymenu at the bottom of the screen.

       -z     Enable ^Z suspension of pico.

       -q     Termcap or terminfo definition for input escape sequences are used in preference to
	      sequences  defined  by default.  This option is only available if pico was compiled
	      with the TERMCAP_WINS define turned on.

       Lastly, when a running pico is disconnected (i.e., receives a SIGHUP), pico will save  the
       current	work  if  needed  before  exiting.  Work is saved under the current filename with
       ".save" appended.  If the current  work	is  unnamed,  it  is  saved  under  the  filename

       The manner in which lines longer than the display width are dealt is not immediately obvi-
       ous.  Lines that continue beyond the edge of the display are indicated by a '$'	character
       at  the end of the line.  Long lines are scrolled horizontally as the cursor moves through

       pico.save	Unnamed interrupted work saved here.
       *.save		Interrupted work on a named file is saved here.
