Mac menus list the keyboard shortcuts for menu items right next to the items.

So do menus on all desktop platforms I've used.

My point is that menus work as a way of exposing functionality and making it discoverable through enumeration in a way that contextual UIs and fashionable techniques of the day don't.

I'm pretty sure that visible shortcuts are a CUA thing. They date way back - even text-mode menu-driven DOS apps had them, e.g. all the Borland IDEs.
