- I assume you mean the "."/DEL key on the keypad, and you're running
- EMACS under X. From what you write I assume that this keycode is
- mapped to the keysym "Delete" at the moment, to do the same as the
- normal "Delete" key.
-
- What you're going to have to do, is to modify the X keymapping of this
- key with 'xmodmap'. Now, Emacs can understand both normal ASCII keys,
- and function keys, for which an escape sequence is sent to the rest of
- EMACS. EMACS does not understand 'symbol' keys (at least, I haven't
- found out how), so, to get EMACS to distinguish this key, you're going
- to have to map it to a function key. Choose a function key which is
- not mapped - X function keys range between F1 and F36. Map this to the
- keycode generated by the keypad 'del' key - this is 57 on a sun type
- 5, I believe it is the same on a type 4. You can use 'xev' to find
- out.
-
- Type the following at a UNIX prompt:
-
- % xmodmap -e 'keycode 57 = F35'
-
- (substitute the correct keycode number and function key)
-
- Now to bind the key. Firstly, make a sparse keymap and bind it to the
- function key escape sequence, esc [.
-
- (setq fnkey-map (make-sparse-keymap))
- (define-key esc-map "[" fnkey-map)
-
- Now you can bind functions to the various escape sequences. We're
- using F35 here as delete, you can also use this technique to bind
- things to other function keys. You can use C-q to find out what
- different function keys send.
-
- (define-key fnkey-map "222z" 'delete-char)
-
- That's all there is to it. Hope this answers your question properly.
