To disable or re-enable this new feature in Ubuntu Unity, install compizconfig-settings-manager first:

sudo apt-get install compizconfig-settings-manager

Launch compizconfig-settings-manager, navigate to Ubuntu Unity Plugin -> Behaviour tab. There “Key to show the HUD” can adjust or disable the HUD key.
