Subject: 24.4.50; key binding not shown in menu item for alias command
Date: Mon, 30 Jun 2014 15:34:03 -0700 (PDT)

emacs -Q

(defun foo () (interactive)(message "Foo"))
(global-set-key "\C-o" 'foo)

(defalias 'bar 'foo)
(define-key menu-bar-edit-menu [bar] '(menu-item "Do It" bar))

In the Edit menu, the key `C-o' is not shown next to item `Do It'.

Also:

(defun toto () (interactive)(message "Toto"))
(define-key menu-bar-edit-menu [toto] '(menu-item "To It" toto))


(defalias 'titi 'toto)
(global-set-key "\C-n" 'titi)

The binding `C-n' is not shown next to menu item `To It'.

Seems like a command alias should be treated like the aliased command
when it comes to showing key bindings in menus.  That would help users.

Is it supposed to?  I'm not sure whether that would be surprising or
not.  Does anybody have an opinion?

Indeed, it isn't clear at all that the expectations in this case are
correct.

To this user, at least, it's clearer that users
will expect the alias's key indication than that
they will expect no key indication.

More importantly, showing the key is more helpful
to users than not showing it.  The key has the
same effect, for users, as using the menu item.

Consider also:

(defun foo () (interactive) (message "FOO"))
(global-set-key "\C-o" 'foo)
(defalias 'bar 'foo)

C-h w bar

  bar is not on any key;
   its alias foo is on C-o

That's nice, complete info.  Both pieces of that
info are appropriate for such a Help command.

Presumably we tell users about the alias binding
to let them know that you can use `C-o' to, in
effect, invoke `bar'.

That's the info that's missing, for a menu item.
