I really liked the old gnome-2 Application menus, which Unity/gnome-3 dropped but which I see I can also get with Lubuntu, classic gnome or cinnamon. I haven't found a way to get to the menus without the mouse though. I used to be able to use alt-key and arrow-keys, and could quickly navigate around.
I don't have time to work thorough all the variantys of ubuntu (and others) and RTFM for all, and my attempts to google-this haven't work.
Anyone know how to get to such a system? Thanks!
