I meant that you can have a command which works in any major mode very
easily:

 (defun Info-summary ()
   "Display a brief summary of all Info commands."
   (interactive)
   (save-window-excursion
     (switch-to-buffer "*Help*")
     (setq buffer-read-only nil)
     (erase-buffer)
-    (insert (documentation 'Info-mode))
+    (insert (documentation major-mode))
     (help-mode)
     (goto-char (point-min))
     (let (ch flag)
       (while (progn (setq flag (not (pos-visible-in-window-p (point-max))))
 		    (message (if flag "Type Space to see more"
 			       "Type Space to return to Info"))
 		    (if (not (eq ?\s (setq ch (read-event))))
 			(progn (push ch unread-command-events) nil)
 		      flag))
 	(scroll-up)))
     (bury-buffer "*Help*")))
