-;; This emacs lisp program can be used to create an emacs lisp file
-;; that defines the mapping of the user's keyboard under X-Windows to
-;; the LK-201 keyboard function keys and keypad keys (around which
-;; EDT has been designed). Please read the "Usage" AND "Known
-;; Problems" sections before attempting to run this program. (The
-;; design of this file, edt-mapper.el, was heavily influenced by
-;; tpu-mapper.el.)
-
-;;; Usage:
+;; [Part of the GNU Emacs EDT Emulation.]
-;; Simply load this file into the X-Windows version of emacs (version 19)

+;; that defines the mapping of the user's keyboard to the LK-201
+;; keyboard function keys and keypad keys (around which EDT has been

+;; below before attempting to run this program. (The design of this
+;; file, edt-mapper.el, was heavily influenced by tpu-mapper.el.)
+
+;; Version 4.0 contains the following enhancements:
+
+;; 1. If you access a workstation using an X Server, note 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.
+
+;; 2. 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, some
+;; terminal/keyboard/window system configurations, which don't
+;; have a complete set of sensible function key map bindings, can
+;; still be configured for EDT Emulation.
+
+
+;; Usage:
+
+;; Simply load this file into emacs (version 19 or higher)
;; using the following command.
;; emacs -q -l edt-mapper.el
-;; The "-q" option prevents loading of your .emacs file (commands therein
-;; might confuse this program).

;; Finally, you will be prompted for the name of the file to store
;; the key definitions. If you chose the default, it will be found
;; and loaded automatically when the EDT emulation is started. If
;; you specify a different file name, you will need to set the
-;; variable "edt-xkeys-file" before starting the EDT emulation.

+
+
+;; Known Problems:
+
+;; Sometimes, edt-mapper will ignore a key you press, and just
+;; continue to prompt for the same key. This can happen when your
+;; window manager sucks up the key and doesn't pass it on to emacs,
+;; or it could be an emacs bug. Either way, there's nothing that
+;; edt-mapper can do about it. You must press RETURN, to skip the
+;; current key and continue. Later, you and/or your local Emacs guru
+;; can try to figure out why the key is being ignored.

- For example, suppose your keyboard has a keycap marked \"Line Del\"
- and you wish to add it to the list of keys which can be customized
- by the EDT Emulation. First, assign a unique single-word name to
- the key for use by the EDT Emulation, let's say \"linedel\", in this
- example. Then, at the \"EDT Key Name:\" prompt, enter \"linedel\",
- followed by a press of the RETURN key. Finally, when prompted,
- press the \"Line Del\" key. You now will be able to bind functions
- to \"linedel\" and \"Gold-linedel\" in edt-user.el in just the same way
- you can customize bindings of the standard LK-201 keys.
-
- When you have no additional function keys to specify, just press
- RETURN at the \"EDT Key Name:\" prompt. (If you change your mind
- AFTER you enter an EDT Key Name and before you press a key at the
- \"Press\" prompt, you may omit the key by simply pressing RETURN at
- the prompt.)
