Shortcut key support for menus

Has anyone used shortcut key support for menus ? (Not sub menus please)

Say I have a menu named file - under which I have 2 submenus “Save …” and “Save As …”

Now the ALT+F key should be equavalent to clicking on File menu and should display dropdown - With “Save” and "Save As " displayed

Well that’s only a windows-specific type of shortcut… On the mac you wouldn’t expect it to do that.

What I should probably do is add a method to the menubar object that makes it open a menu - then you could create a shortcut that triggers this.

I’d use that, not for shortcuts, but for something else; was looking for such a method about a week ago.
