Hello,

What is the correct way to bind a key modified by both the control and
the meta key?  I failed to find an example in the help texts and the
following command doesn't work:

(global-set-key "\C-M-7" 'shell)

When I try the following, the binding is listed when accessed with C-h
b, but actually pressing the keys just gets "C-M-7" printed in the
minibuffer:

(global-set-key [C-M-7] 'shell)

Any help would be greatly appreciated,

Chris

Have a look at the info page "How do I bind a combination of modifier key
and function key?" under "Key Bindings" in the Emacs FAQ.

Another useful trick is to do the binding interactively with M-x
global-set-key, etc., then use C-x <esc> <esc> (`repeat-complex-command')
to see what it looks like in lisp.

"\C-\M-7" is a correct syntax.

At least your operating system seems to generate something sensible for
this key event.

After typing the keys, do C-h l (`view-lossage') to check what Emacs
_really_ saw.

Try C-h c followed by C-M-7.

Try

   (global-set-key (kbd "C-M-7") 'shell)

I recommend the [(control ?x) (control meta ?7)] syntax.
The kbd syntax is also good.

Thank you all for your help; the advice above actually worked in my
case, other examples didn't strangely.  In case you are curious, I
ended up with the command looking like this:

;(global-set-key (quote [-67108809]) (quote shell))

That is not portable, which is why the "\M-\C-x", [?\M-\C-x], and

(meta control ?x) syntaxes are preferred.

M-x global-set-key ...
C-x ESC ESC ...
