-
- ;;; Commentary:
-
- ;; 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:
-
- ;; Simply load this file into the X-Windows version of emacs (version 19)
- ;; 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).
-
- ;; An instruction screen showing the typical LK-201 terminal functions keys
- ;; will be displayed, and you will be prompted to press the keys on your
- ;; keyboard which you want to emulate the corresponding LK-201 keys.
-
- ;; 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.
- ;; Here's how you might go about doing that in your .emacs file.
-
- ;; (setq edt-xkeys-file (expand-file-name "~/.my-emacs-x-keys"))
-
- ;;; 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 X guru can try to figure out why the key is being ignored.

- EDT MAPPER
-
- You will be asked to press keys to create a custom mapping (under
- X-Windows) of your keypad keys and function keys so that they can emulate
- the LK-201 keypad and function keys or the subset of keys found on a
- VT-100 series terminal keyboard. (The LK-201 keyboard is the standard
- keyboard attached to VT-200 series terminals, and above.)
-
- 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 X guru can try to figure out why the key is being ignored.
-
- Start by pressing the RETURN key, and continue by pressing the keys
- specified in the mini-buffer. If you want to entirely omit a key,
- because your keyboard does not have a corresponding key, for example,
- just press RETURN at the prompt.

- ADDITIONAL FUNCTION KEYS
-
- Your keyboard may have additional function keys which do not
- correspond to any LK-201 keys. The EDT Emulation can be
- configured to recognize those keys, since you may wish to add your
- own key bindings to those keys.
-
- 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.)
