Nothing. The binding of <delete> assumes a standard
Emacs keymap. You will have to change that mapping as well. 

In general, expect to change lots of bindings, and expect changes to
cascade. You will probably have a small maintenance burden when
you are done.

This is not part of the default config, so it must come from your .emacs
or the default.el or site-start.el files (or you're running a modified
version of Emacs as is too often the case with standard distributions
not able to resist the temptation to "fix" things without understanding the
implications).

Try to start your emacs with `emacs -q --no-site-file' and see if
the problem is still there.

You're right. That binding was in /etc/emacs/site-start.el

(Xlaunch (define-key global-map [(delete)] "\C-d"))

which is the mandrake configuration file for emacs. From this I 
understand rewritting

(Xlaunch (define-key global-map [(delete)] 'delete-char))

is more appropiate isn't it?


Thanks also to Barry for reminding that delete-char exists.

I think it's more appropriate to just keep the default, rather than
any of those two alternatives.
Complaining to Mandrake is also a good thing to do.

Here is the new binding of <delete> 	is there a nicer way to write it?

(define-key global-map [delete] (lambda () (interactive) 	   	 
(delete-backward-char -1)))

Cheers

unexpected Del behaviour after C-d binding

[Dani Barral]

Hi,

I'm trying to configure the keyboard of my laptop into something more 
confortable for my hands. First I want to rebind some emacs commands and 
after I'll exchange some control,alt,... keys in X.

The problem I having with GNU Emacs 21.2.1 is that the behaviour of the 
Del key changes after this:

(global-unset-key "\C-d")
(global-set-key "\C-d" 'next-line)

Now everytime I press Del next-line is executed. However C-h Del returns:
<delete> runs the command "^D"
    which is a keyboard macro.

Could anybody what's wrong with those two bindings above?

Cheers

Dani
