help with global-set-key

[Rich E]

Hi,

I found this custom command at http://www.crsr.net/Notes/Emacs.html :

;;; Use "%" to jump to the matching parenthesis.
(defun goto-match-paren (arg)
  "Go to the matching parenthesis if on parenthesis, otherwise insert
the character typed."
  (interactive "p")
  (cond ((looking-at "\\s\(") (forward-list 1) (backward-char 1))
    ((looking-at "\\s\)") (forward-char 1) (backward-list 1))
    (t                    (self-insert-command (or arg 1))) ))
(global-set-key "%" 'goto-match-paren)



I am trying to change the global-set-key to something like "\C-.", but this isn't an acceptable 'string and I don't know why.  Can anyone help?

regards,
Rich
