How do you disable Alt as the HUD key in 13.04
I just tried it in CCSM in 13.04 and disabling works. Here's what I do.
Open ccsm and select the Ubuntu Unity plugin.
Click the Edit button (Pencil icon) and in the dialog that appears, delete the text. Just leave it empty and click save.
- That's all. You should see now that the HUD shortcut is disabled.
I. Install Ubuntu Tweak
sudo apt-get install unity-tweak-tool
II. Open it and go to Unity > Additional
III. Change keyboard key to invoke HUD or disable it with backspace
IV. Log out
