A number of games, Emacs, and the terminal make extensive use of the Alt key. Can Unity be configured to respect this key, rather than launching the HUD with it?
Open the System Settings application either by going to
Then go to
If you set it to Alt manually, the setting distinguishes between the left and right Alt key. So if you want to maintain general behaviour and still use Alt combinations, this may be an alternate solution for you.

You can use compizconfig-settings-manager to change the key used to show the HUD.
To install it, run the following command in a terminal:
After installing it, open it and go to Ubuntu Unity Plugin.
Click on the button for the option Key to show the HUD and a dialog similar to the one shown below will appear.
Click on Grab key combination and press your desired new key combination and press enter. After that, click on OK button and the new key combination will trigger the HUD from now on.
Well it's Called HUD. The new feature of Unity.
To stop it from appearing you can disable it's key binding in keyboard shortcuts.
Open system settings by going to
In system settings select
In Ubuntu 12.04 I changed shortcut for summoning HUD in
Now my left Alt is happy again :-)
