C-delete in Emacs 23.1

C-delete in Emacs 23.1

[cmr.Pent]

In new Emacs the keybinding C-delete is assigned to kill-visual-line
command, while it used to be assigned to kill-word-backward. My
attempt to override the binding using global-set-key failed. How do I
revert the C-delete behavior?

I'm ready to provide any additional info,
Andrey

See:

• How To Reclaim Keybindings In Emacs
  http://xahlee.org/emacs/ergonomic_emacs_keybinding_minibuffer.html

• How to Define Keyboard Shortcuts in Emacs
  http://xahlee.org/emacs/keyboard_shortcuts.html

i'd recommend remap the keys so that

E R       I
D F     J K L

where the I J K L is cursor moving keys with Alt down. And
E R is deleting word left/right,
D F is deleting char left/right.

For the elisp code, see:

I don't know how it happens, but guess you bind <C-delete> to
`kill-line' and turn `visual-line-mode' on.  Anyway what binds
a key to `kill-visual-line' seems to be `visual-line-mode-map'
only, so this will do the trick:

(define-key visual-line-mode-map [(control delete)] 'backward-kill-word)

No, `C-<delete>' is normally bound to `kill-word' while `M-<delete>' is
bound to `backward-kill-word'.  `kill-visual-line' is bound to `C-k' and
`<deleteline>' if `visual-line-mode' is activated.  If it's not active,
`kill-visual-line' isn't bound to any key.

Is it really different at you?  Please check with "emacs -Q".

That's because major and minor mode bindings override global bindings.
And `kill-visual-line' is bound in `visual-line-mode-map'.

I think the thing that you don't like is `visual-line-mode', so I'd
suggest to switch that off.

Thanks for your suggestions!

Unfortunately, neither helped. But I was able to track down the
problem ;-) It turns out that the problem only reveals itself in
emacsclient. I filed a bug report (http://emacsbugs.donarmstrong.com/
cgi-bin/bugreport.cgi?bug=1960).

Just for the record, that's what C-h k C-backspace outputs on my
system:

emacs 22.2 -Q, emacs 22.2:

<C-backspace> runs the command backward-kill-word
  which is an interactive compiled Lisp function in `simple.el'.
It is bound to <C-backspace>, M-DEL.
(backward-kill-word arg)

Kill characters backward until encountering the beginning of a word.
With argument, do this that many times.

emacs 23.1 -Q, emacs 23.1:

<C-backspace> runs the command backward-kill-word, which is an
interactive compiled Lisp function.

It is bound to <C-backspace>, M-DEL.

(backward-kill-word arg)

Kill characters backward until encountering the beginning of a word.
With argument arg, do this that many times.

emacs 23.1 --daemon  +  emacsclient -c:

<C-backspace> runs the command kill-visual-line, which is an
interactive compiled Lisp function.

It is bound to <deleteline>, <C-backspace>, C-k.

(kill-visual-line &optional arg)

Kill the rest of the visual line.
If there are only whitespace characters there, kill through the
newline as well.

...

Good luck,
Andrey
