In Ubuntu System Settings >> Keyboard >> Shortcuts I can't enable the "run command prompt" shortcut neither the "show the activities overview" shortcut.
They are both in italics, unlike all other shortcuts.
The "run command prompt" shortcut is kinda important for my work. I've been searching all over the web, but can't find any solution.
I reinstalled Ubuntu, and now I can't enable these keys - was able to do that in previous installation.
Really hoping that someone has experienced the same problem as me, and has been able to solve the problem.
Try change this using ccsm (CompizConfig Settings Manager).
$ ccsm
If you have installed a 'Ubuntu Unity Plugin' bind hotkey using this plugin at 'Behaviour' tab.
