ELLE  (ELLE  Looks  Like Emacs) is an Emacs clone for ELLE is not
full Emacs but it has about 80 commands and is quite fast.  Mined
only  has  a small number of commands.	All of them are either of
the form CTRL-x or are on the numeric  keypad.	 Emacs,  in  con-
trast,	has  so  many  commands, that not only are all the CTRL-x
commands used up, but so are all the ESC x (escape followed by x;
escape	is  not  a shift character, like CTRL).  Even this is not
enough, so CTRL-X is used as a prefix  for  additional	commands.
Thus  CTRL-X  CTRL-L is a command, and so is CTRL-X K.	Note that
what is conventionally written as CTRL-X K really means CTRL-X k.
In some contexts it is traditional to write CTRL-X as ^X.  Please
note that they mean the same thing.  As a result, many Emacs com-
mands  need  three  or	four key strokes to execute.  Some people
think 3-4 key strokes is too many.  For this  reason,  Emacs  and
ELLE  allow users to assign their own key bindings.  In ELLE this
is done with user profiles.  A user profile  is  a  file  listing
which  function is invoked by which key stroke.  The user profile
is then compiled by a program  called  ellec  into  binary  form.
When ELLE starts up it checks to see if a file .ellepro.b1 exists
in $HOME.  If it does, this file is read in and overrides the de-
fault bindings.  A user profile that simulates the mined commands
fairly well is provided.  Its installation  is	described  later.
If  you  have  never used Emacs, it is suggested that you use the
mined profile.	If you normally use Emacs, then  do  not  install
the  mined  profile.   You  can  also  make your own using ellec.
There is no Mock Lisp.	ELLE has a character-oriented view of the
world, not a line oriented view, like ed.  It does not have magic
characters for searching.  However, you  can  use  line  feed  in
search	patterns.   For example, to find a line consisting of the
three characters foo all by themselves on a line, using the mined
bindings (see below), use the pattern: CTRL- CTRL-J f o o CTRL-
CTRL-J.  The CTRL- means to interpret the next character literal-
ly,  in this case it is CTRL-J, which is line feed.  You can also
search for patterns involving multiple lines.	For  example,  to
find a line ending in an x followed by a line beginning with a y,
use as pattern: x CTRL- CTRL-J y.  These are the key bindings  if
the binary user profile, .ellepro.b1, is installed in $HOME.  The
ESCAPE key followed by a number followed by a command causes that
command  to  be executed number times.	This applies both to con-
trol characters and insertable characters.  CTRL-X  refers  to	a
control  character.  ESC x refers to an escape character followed
by x.  In other words, ^X is a synonym for CTRL-X.  ^X	Y  refers
to  CTRL-X  followed  by  y.  To abort the current command and go
back to the main loop of the editor,  type  CTRL-G,  rather  than
CTRL-.   Only	a  few commands are of the form CTRL-X Y.  All of
these are also bound to CTRL-X CTRL-Y, so you can hold down  CTRL
and  then hit X Y, or release control after the X, as you prefer.
The key bindings that are not listed should not be used.  Some of
them  actually do things.  For example, the ANSI escape codes ESC
[ x are bound to ^X Y for a variety of y.  Some commands work  on
regions.   A  region  is defined as the text between the most re-
cently set mark and the cursor.  If the  mined	profile,  is  in-
stalled in your home directory, the following commands will work.

The  major  differences  between  ELLE with the mined profile and
mined itself are:

  1. The definition of a word is different for forward and backward word
  2. The mark is set with CTRL-^ instead of CTRL-@
  3. Use CTRL-G to abort a command instead of CTRL-
  4. Use CTRL- to literally insert the next character, instead of ALT
  5. CTRL-E adjusts the window to put the cursor in the middle of it
  6. To get and insert a file, use ESC G instead of CTRL-G
  7. To go to line n, type ESC n CTRL-[ instead of CTRL-[ n
  8. You exit with CTRL-X CTRL-X and then answer the question with y.
  9. There are many new commands, windows, larger files, etc.

If you do not have the mined profile installed, you get the stan-
dard  Emacs  key bindings.  These are listed below.  Commands not
listed are not implemented.

It is possible to create your own user profile.  The mechanism is
different  from  Emacs, since ELLE does not have Mock Lisp.  Pro-
ceed as follows.  Modify .ellepro.e to suit your taste.   Install
.ellepro.e  in	your  home  directory.	 Type:	Check  to  see if
.ellepro.b1 has been created.  If it has, you are  ready  to  go.
