无法在GNU Emacs 23中以GDB模式自定义本地键绑定

Question

I've added the code below to my .emacs to bind the command gdb-restore-windows to the key sequence Cc C-. . But when I start GDB mode and type the key sequence, I always get the prompt

Cc C-. is undefined.

(defun xyt/gdb-hotkey-hook ()
  (local-set-key (kbd "C-cC-.") 'gdb-restore-windows))

(add-hook 'gdb-mode-hook 'xyt/gdb-hotkey-hook)

Answer 1

正如@artscan在问题评论中指出的那样，我错过了一个空格。
