I'm running Cylon Linux 12.04 and some of the keys on the keyboard don't function properly, the Tab key brings up the Search Window and the 0 on the keypad brings up that window that lists the 4 desktops in a 3-D format showing each desktop in real mode what is on it and shows any action like a video playing I think it is called the Heads Up Display (HUD). I tried the keyboard short cut setting and did not find anything assigned to the 0 key on the keypad or the Tab Key assigned to bringing up the search window but did find that it shows "HUD" assigned to Atl S and not the Tab Key.
This only happens when I have Gnome Advanced as tghe Desktop Interface but all other desktop interfaces including Gnome Classic no effect.:?:(
Thanks
Fixed it I changed the Keyboard Shortcut
