キーバインド変更

標準でやってるのはこれぐらいかなぁ？

(keyboard-translate ?\C-h ?\C-?)
(global-set-key "\C-h" nil)
(global-set-key "\C-ch" 'help-command)
(global-set-key [f1] 'help-for-help)
(global-set-key "\M-?" 'help-for-help)
(global-set-key "\C-cg" 'goto-line)
(global-set-key "\C-z" 'undo)
(global-set-key "\C-x\C-b" 'buffer-menu-other-window)
