How to bind the keyboard 'C-;'

How to bind the keyboard 'C-;'

[Vols]

Hi, group

I want the keyboard binding 'Control  ;' , for example, I tried:
(global-set-key  "\C-;" 'kill-this-buffe)
It doesn't work and comes with a "invalid modifier in string" error.

Actually i want to use 'C-;' to comment current line. (M-; add comment
at the end of the line). I used :

(global-set-key  "\C-;" 'my-comment-current-line)
(defun my-comment-current-line ()
  (interactive)
  (comment-region (line-beginning-position) (line-end-position)))

Thanks.
Vol.

You must avoid the string syntax when binding non-ASCII characters.
(kbd "C-;") and [(control \;)] should work.

and [?\C-;]

Can anyone explain why the semicolon does not need to be backslashed
there?

Well, it kind of does: the `read' function will not need a backslash because
when it sees "?\C-" is knows that what follows can't be a comment (because
"?\C-" on its own is not a valid lexeme).

But emacs-lisp-mode doesn't understand this (because it doesn't use the full
builtin lisp parser), so font-lock and syntax-based navigation (e.g. C-M-f)
will not treat it correctly if the ; is not escaped.
