   Hi all,

   I am using emacs 18.58 on a SUN 4 (Sparc 1) with a type 4 keyboard.

   I would like to remap the DEL key on the keypad from delete-backward-char
   to delete-char.  I have tried in my .emacs
   (global-set-key "DEL" 'delete-char)
   (global-set-key "\DEL" 'delete-char)
   etc. to no avail.

To insert the delete key between the quotes, move there and type
   C-Q <DEL>
(were by <DEL> I mean pressing the DEL key).


   I did notice that I could do a 
   M-x local-set-key DEL delete-char
   while running emacs and this worked OK.

After you successfully do a command with M-X, if you want to copy that
command into your .emacs file, do
  C-X <ESC>
(which is repeat-complex-command).  This throws you into the
minibuffer with a lisp version of your last command.  Copy the line
into the kill buffer (e.g. with
  C-A C-K
) and exit the minibuffer with C-G.  Now you can paste the command
into your .emacs file.

Using "\C-?" should also work.  C-? is fairly standard notation for the DEL
character. 

However, this will not solve your problem, because most major modes redefine
the binding of the DEL character one of the variations of
delete-backward-char, like backward-delete-char-untabify, in the major mode
local map, which overrides the global map.

Which changed the binding in the active buffer at the time you executed the
local-set-key function.  Other buffers were not affected.

To change the binding in major modes that you use, you will have to use the
setup hook for each major mode and assign the hook to a function which
executes the local-set-key function to change the binding of DEL.

Try 
	(global-set-key "\C-?" 'delete-char)

\C-? is translated to delete in quoted strings. Alternatively you can
use ^Q (quoted-insert) to but the real delete into the string.

Hope this helps,
Ed

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.

If I understand you right, you want:
 Delete to delete the character you stand on, and
 Backspace to delete the previous character?

Well I also use a type 4 keyboard and if you use for example xev to check the
code which the keyboard returns you'll see that they are the same for Bakspace and
Delete so effectively it is only one key with two buttons. And thus they can`t work as 
two different buttons.

But if you`ve found a way to separate them please mail me.

The reason global-set-key doesn't work is that your DEL key (\C-?) is
overridden locally by each of the modes.  If you want to change it,
you have to do it with mode hooks.  For example:

(defun reset-del ()
  (local-set-key "\C-?" 'delete-char))

(setq text-mode-hook 'reset-del)
