Enable "run command prompt" shortcut in Ubuntu

Question

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.

Answer 1

Erm...:

So, you click where it says Disabled, and you press the desired hotkey (usually, Alt+F2 for Run, e.g.)

Is that not working for you?

PS. if not, consider just adding custom shortcuts to do what you want. It may be you are using Unity, which might not readily implement these commands. You may consider switching to one of the 'old style' desktops that still support Gnome-style interface:

• Xubuntu (Xfce desktop, now with Linus endorsement :))
• Linux Mint 12
• Linux Mint Debian edition

Answer 2

Try change this using ccsm (CompizConfig Settings Manager).

$ ccsm

1. Click 'Gnome Compatibility' (make sure that is enabled)
2. 'General' tab:
3. Set desired hotkey for 'Run Dialog' .

If you have installed a 'Ubuntu Unity Plugin' bind hotkey using this plugin at 'Behaviour' tab.

Answer 3

In the Keyboard settings dialog, if we click on the entire row as suggested on the dialog, it doesn't work. In fact, we must click on the second column indicating the value of the corresponding shortcut key (e.g., Disabled, Ctrl+Alt+D). This will allow us to edit or modify the new shortcut by entering the new keys.
