Keyboard shortcuts don't work in activities overview

[tuxor1337 web de]

Hi all,

using Fedora 17 and Gnome 3.4, I can't use any sort of hotkey or 
keyboard shortcut in activities overview.

- Any custom shortcuts don't work (like shortcuts that are supposed to 
start certain applications).

- volume hotkeys on my laptop's keyboard don't trigger any action in 
overview, even though they work fine in every other situation. same for 
the brightness adjustment keys.

- "print screen" or ctrl+"print screen" doesn't take a screenshot while 
in activities overview.


Is this a known limitation of gnome? can it be fixed and if yes, how? or 
is it a Fedora related problem? in the last case I'm going to report 
this as a bug on redhat bugzilla.

thanks in advance,

thomas
