30 ;; This emacs lisp program can be used to create an emacs lisp file
|
|
|
31 ;; that defines the mapping of the user's keyboard under X-Windows to
|
|
|
32 ;; the LK-201 keyboard function keys and keypad keys (around which
|
|
|
33 ;; EDT has been designed). Please read the "Usage" AND "Known
|
|
|
34 ;; Problems" sections before attempting to run this program. (The
|
|
|
35 ;; design of this file, edt-mapper.el, was heavily influenced by
|
|
|
36 ;; tpu-mapper.el.)
|
|
|
37
|
|
|
38 ;;; Usage:
|
|
|
39
|
|
|
40 ;; Simply load this file into the X-Windows version of emacs (version 19)
|
|
|
41 ;; using the following command.
|
|
|
42
|
|
|
43 ;; emacs -q -l edt-mapper.el
|
|
|
44
|
|
|
45 ;; The "-q" option prevents loading of your .emacs file (commands therein
|
|
|
46 ;; might confuse this program).
|
|
|
47
|
|
|
48 ;; An instruction screen showing the typical LK-201 terminal functions keys
|
|
|
49 ;; will be displayed, and you will be prompted to press the keys on your
|
|
|
50 ;; keyboard which you want to emulate the corresponding LK-201 keys.
|
|
|
51
|
|
|
52 ;; Finally, you will be prompted for the name of the file to store
|
|
|
53 ;; the key definitions. If you chose the default, it will be found
|
|
|
54 ;; and loaded automatically when the EDT emulation is started. If
|
|
|
55 ;; you specify a different file name, you will need to set the
|
|
|
56 ;; variable "edt-xkeys-file" before starting the EDT emulation.
|
|
|
57 ;; Here's how you might go about doing that in your .emacs file.
|
|
|
58
|
|
|
59 ;; (setq edt-xkeys-file (expand-file-name "~/.my-emacs-x-keys"))
|
|
|
60
|
|
|
61 ;;; Known Problems:
|
|
|
62
|
|
|
63 ;; Sometimes, edt-mapper will ignore a key you press, and just continue to
|
|
|
64 ;; prompt for the same key. This can happen when your window manager sucks
|
|
|
65 ;; up the key and doesn't pass it on to emacs, or it could be an emacs bug.
|
|
|
66 ;; Either way, there's nothing that edt-mapper can do about it. You must
|
|
|
67 ;; press RETURN, to skip the current key and continue. Later, you and/or
|
|
|
68 ;; your local X guru can try to figure out why the key is being ignored.

140 X-Windows) of your keypad keys and function keys so that they can emulate

141 the LK-201 keypad and function keys or the subset of keys found on a

348 ADDITIONAL FUNCTION KEYS
|
|
|
349
|
|
|
350 Your keyboard may have additional function keys which do not
|
|
|
351 correspond to any LK-201 keys. The EDT Emulation can be
|
|
|
352 configured to recognize those keys, since you may wish to add your
|
|
|
353 own key bindings to those keys.
|
|
|
354
|
|
|
355 For example, suppose your keyboard has a keycap marked \"Line Del\"
|
|
|
356 and you wish to add it to the list of keys which can be customized
|
|
|
357 by the EDT Emulation. First, assign a unique single-word name to
|
|
|
358 the key for use by the EDT Emulation, let's say \"linedel\", in this
|
|
|
359 example. Then, at the \"EDT Key Name:\" prompt, enter \"linedel\",
|
|
|
360 followed by a press of the RETURN key. Finally, when prompted,
|
|
|
361 press the \"Line Del\" key. You now will be able to bind functions
|
|
|
362 to \"linedel\" and \"Gold-linedel\" in edt-user.el in just the same way
|
|
|
363 you can customize bindings of the standard LK-201 keys.
|
|
|
364
|
|
|
365 When you have no additional function keys to specify, just press
|
|
|
366 RETURN at the \"EDT Key Name:\" prompt. (If you change your mind
|
|
|
367 AFTER you enter an EDT Key Name and before you press a key at the
|
|
|
368 \"Press\" prompt, you may omit the key by simply pressing RETURN at
|
|
|
369 the prompt.)
