============================================================================
I. OVERVIEW:
This version of the EDT emulation package for GNU Emacs is a substantially
enhanced version of the original. A large part of the original can still be
found here, of course, but much of it has been modified and quite a bit is
new. Many of the ideas found here are borrowed from others. In particular,
some of the code found here was drawn from an earlier re-write of the EDT
package done at DSC in 1989 by Matthew Frohman.
This is Version 4.0 of the EDT Emulation for Emacs 19 and above.
It comes with special functions which replicate nearly all of EDT's
keypad mode behavior. It sets up default keypad and function key
bindings which closely match those found in EDT. Support is
provided so that users may reconfigure most keypad and function key
bindings to their own liking.
NOTE: Version 4.0 contains several enhancements. See the
Enhancements section below for the details.
Quick Start:
To start the EDT Emulation, first start Emacs and then enter
M-x edt-emulation-on
Send bug fixes, suggestions for enhancements, and corrections to this
documentation to Kevin Gallagher (kevingal@onramp.net).
to begin the emulation. After initialization is complete, the
following message will appear below the status line informing you
that the emulation has been enabled: "Default EDT keymap active".
You can have the EDT Emulation start up automatically, each time
you initiate a GNU Emacs session, by adding the following line to
your .emacs file:
(add-hook term-setup-hook 'edt-emulation-on)
IMPORTANT: Be sure to read the rest of this file. It contains very
useful information on how the EDT Emulation behaves and how
to customize it to your liking.
The EDT emulation consists of the following files:
edt-user.doc - User instructions (which you are reading now)
edt.el - EDT Emulation Functions and Default Configuration
edt-lk201.el - Support for DEC LK-201 Keyboards
edt-vt100.el - Support for DEC VT-100 (and above) terminals
edt-mapper.el - Support for Keyboards used under X Windows
edt-pc.el - Support for the PC AT Keyboard under MS-DOS
edt-user.doc - User Instructions and Sample Customization File
edt.el - EDT Emulation Functions and Default Configuration
edt-lk201.el - Built-in support for DEC LK-201 Keyboards
edt-vt100.el - Built-in support for DEC VT-100 (and above) terminals
edt-pc.el - Built-in support for PC 101 Keyboards under MS-DOS
edt-mapper.el - Create an EDT LK-201 Map File for Keyboards Without
Built-in Support
Several goals were kept in mind when making this version:
1. Emulate EDT Keypad Mode commands closely so that current
EDT users will find that it easy and comfortable to use
GNU Emacs with a small learning curve;
Enhancements:
Version 4.0 contains the following enhancements:
1. Scroll margins at the top and bottom of the window are now
supported. (The design was copied from tpu-extras.el.) By
default, this feature is enabled with the top margin set to
10% of the window and the bottom margin set to 15% of the
window. To change these settings, you can invoke the function
edt-set-scroll-margins in your .emacs file. For example, the
following line
(edt-set-scroll-margins "20%" "25%")
sets the top margin to 20% of the window and the bottom margin
to 25% of the window. To disable this feature, set each
margin to 0%. You can also invoke edt-set-scroll-margins
interactively while EDT Emulation is active to change the
settings for that session.
NOTE: Another way to set the scroll margins is to use the
Emacs customization feature (not available in Emacs 19) to set
the following two variables directly:
edt-top-scroll-margin and edt-bottom-scroll-margin
Enter the Emacs `customize' command. First select the Editing
group and then select the Emulations group. Finally, select
the Edt group and follow the directions.
2. The SUBS command is now supported and bound to GOLD-Enter by
default. (This design was copied from tpu-edt.el.) Note, in
earlier versions of EDT Emulation, GOLD-Enter was assigned to
the Emacs function `query-replace'. The binding of
`query-replace' has been moved to GOLD-/. If you prefer to
restore `query-replace' to GOLD-Enter, then use an EDT user
customization file, edt-user.el, to do this. See edt-user.doc
for details.
3. EDT Emulation now also works in XEmacs, including the
highlighting of selected text.
4. If you access a workstation using an X Server, observe that
the initialization file generated by edt-mapper.el will now
contain the name of the X Server vendor. This is a
convenience for those who have access to their Unix account
from more than one type of X Server. Since different X
Servers typically require different EDT emulation
initialization files, edt-mapper.el will now generate these
different initialization files and save them with different
names. Then, the correct initialization file for the
particular X server in use is loaded correctly automatically.
5. Also, edt-mapper.el is now capable of binding an ASCII key
sequence, providing the ASCII key sequence prefix is already
known by Emacs to be a prefix. As a result of providing this
support, some terminal/keyboard/window system configurations,
which don't have a complete set of sensible function key
bindings built into Emacs in `function-key-map', can still be
configured for use with EDT Emulation. (Note: In a few rare
circumstances this does not work properly. In particular, it
does not work if a subset of the leading ASCII characters in a
key sequence are recognized by Emacs as having an existing
binding. For example, if the keypad 7 (KP-7) key generates
the sequence \"<ESC>Ow\" and \"<ESC>O\" is already bound to a
function, pressing KP-7 when told to do so by edt-mapper.el
will result in edt-mapper.el incorrectly mapping \"<ESC>O\" to
KP-7 and \"w\" to KP-8. If something like this happens to
you, it is probably a bug in the support for your keyboard
within Emacs OR a bug in the Unix termcap/terminfo support for
your terminal OR a bug in the terminal emulation software you
are using.)
6. The edt-quit function (bound to GOLD-q by default) has been
modified to warn the user when file-related buffer
modifications exist. It now cautions the user that those
modifications will be lost if the user quits without saving
those buffers.
Goals:
1. Emulate EDT Keypad Mode commands closely so that current EDT users
will find that it easy and comfortable to use GNU Emacs with a
small learning curve;
2. Make it easy for a user to customize EDT emulation key
bindings without knowing much about Emacs Lisp;

5. Provide an easy way to restore ALL original Emacs key bindings,
just as they existed before the EDT emulation was first invoked.
6. Support GNU Emacs 19. (Support for GNU Emacs 18 has been dropped.
Also, although there is some code designed to support Xemacs 19
(formerly Lucid Emacs), this is not fully implemented at this
time.
6. Support GNU Emacs 19 and higher. (GNU Emacs 18 and below is no
longer supported.) XEmacs 19, and above, is also supported.
7. When running under X, support highlighting of marked text.
7. Supports highlighting of marked text within the EDT emulation on
all platforms on which Emacs supports highlighting of marked text.
8. Handle terminal configuration under X interactively when the
emulation is invoked for the first time.
8. Handle terminal configuration interactively for most terminal
configurations, when the emulation is invoked for the first time.
9. Support a PC AT keyboard under MS-DOS.
II. TERMINALS/KEYBOARDS SUPPORTED:
Keyboards used under X Windows are supported via the edt-mapper function. The
first time you invoke the emulation under X, the edt-mapper function is run
automatically and the user is prompted to identify which keys the emulation is
to use for the standard keypad and function keys EDT expects (e.g., PF1, PF2,
etc.). This configuration is saved to disk read each time the emulation is
invoked.
Keyboards used under a Window System are supported via the edt-mapper function.
The first time you invoke the emulation under a window system, the edt-mapper
function is run automatically and the user is prompted to identify which keys

(e.g., PF1, PF2, KP0, KP1, F1, F2, etc.). This configuration is saved to disk
read each time the emulation is invoked.
In character oriented connections not running a window manager, the following
terminals/keyboards are supported. (1) DEC VT-100 series and higher. This
includes well behaved VT clones and emulators. If you are using a VT series
terminal, be sure that the term environment variable is set properly before
invoking emacs. (2) PC AT keyboard under MS-DOS.

IV. SPECIAL NOTES FOR SOME PLATFORMS:
Sun Workstations running X:
Some earlier Sun keyboards do not have arrow keys separate from the
keypad keys. It is difficult to emulate the full EDT keypad and still

Some earlier Sun keyboards do not have arrow keys separate from the keypad
keys. It is difficult to emulate the full EDT keypad and still retain use
of the arrow keys on such keyboards.
The Sun Type 5 keyboard, however, does have separate arrow keys. This
makes it a candidate for setting up a reasonable EDT keypad emulation.
Unfortunately, Sun's default X keynames for the keypad keys don't permit
GNU Emacs to interpret the keypad 2, 4, 6, and 8 keys as something other
than arrow keys, nor use all the top row of keys for PF1 thru PF4 keys.
Here's the contents of an .xmodmaprc file which corrects this problem for
Sun Type 5 keyboards:
The Sun Type 5 and other more recent Sun keyboards, however, do have
separate arrow keys. This makes them candidates for setting up a
reasonable EDT keypad emulation.
Depending upon the configuration of the version of X installed on your
system, you may find the default X keynames for the keypad keys don't
permit Emacs to interpret some or all the keypad keys as something other
than arrow keys, numeric keys, Home, PgUP, etc. Both Sun and HP have been
particularly guilty of making bizarre keysym assignments to the keypad
keys.
In most cases, the X Windows command, xmodmap, can be used to correct the
problem. Here's a sample .xmodmaprc file which corrects this problem on
one Sun workstation configuration using an older SunOS release configured

Scroll margins at the top and bottom of the window are now supported. (The
design was copied from tpu-extras.el.) By default, this feature is enabled
with the top margin set to 10% of the window and the bottom margin set to 15%
of the window. To change these settings, you can invoke the function
edt-set-scroll-margins in your .emacs file. For example, the following line
(edt-set-scroll-margins "20%" "25%")
sets the top margin to 20% of the window and the bottom margin to 25% of the
window. To disable this feature, set each margin to 0%. You can also invoke
edt-set-scroll-margins interactively while EDT Emulation is active to change
the settings for that session.
NOTE: Another way to set the scroll margins is to use the Emacs customization
feature (not available in Emacs 19) to set the following two variables
directly:
edt-top-scroll-margin and edt-bottom-scroll-margin
Enter the Emacs `customize' command. First select the Editing group and then
select the Emulations group. Finally, select the Edt group and follow the
directions.

;;; Commentary:
;; This file contains GNU Emacs User Custom EDT bindings and functions. In
;; this example file, there is no special test for the type of terminal being
;; used. The assumption is that all key bindings here apply to all terminals
;; that may be used. (In fact, it was written by an individual who uses only
;; VT series terminals when logging into a VAX.)
;;
;; WARNING: Each of the three functions, edt-bind-function-key,
;; edt-bind-gold-key, and edt-bind-standard-key, has an optional
;; last argument. The optional argument should NOT be used in
;; edt-user.el! When the optional argument is missing, each
;; function knows to make the key binding part of the user's EDT
;; custom bindings, which is what you want to do in edt-user.el!
;;
;; The EDT default bindings are set up in edt.el by calling these
;; same functions with the optional last argument set to "t". So, if
;; you decide to copy such function calls from edt.el to edt-user.el
;; for subsequent modification, BE SURE TO DELETE THE "t" AT THE END
;; OF EACH PARAMETER LIST!
