Comment 5 for bug 334544

The most important thing is that you can open Applications and then use "right arrow" three times to get to this menu. If I had to pick a key though I would pick the SUPER-key (aka. the Windows key); but maybe the SUPER-key should be saved for a more common use case though. The SUPER-key is nice though because it's conceptually reserved for the shell (i.e. it will pretty much never be bound to something inside an application window).
