How to install HUD in Ubuntu 12.04 LTS

The new approach of interacting with menus, HUD, has just been announced, but already, Ubuntu developers have put together the code in a PPA in order to gather feedback needed probably as an answer to the question: Will HUD land in Ubuntu 12.04 LTS?

After HUD is installed, in order to use it, one must press the default shortcut, Alt, otherwise is absent from the desktop, appearing only on-demand, meaning the new or more traditional users have the option to slowly/progressively accommodate themselves with HUD.

The look is Unity-like, following the same chameleonic behavior of borrowing wallpaper's colors, strengthening desktop's consistency and integration.

Despite being a prototype, HUD posses already an enhanced intelligence in guessing one's intentions when typing and accurately provides proper actions/apps in relation with the typed word.

One interesting attribute of HUD is its search mechanism/ability to gather data acting as a scanner differently from then semantic-based launchers (Synapse, Kupfer, etc), arranging the data in form of related categories, one could name this a complete search (in apps, menus, related menus' entries, related configuration options, related actions, etc).

HUD comes packed inside a new Unity 3D, 5.1 version, and, at the moment, with only one tweakable option, under CompizConfig Settings Manager-->Ubuntu Unity Plugin-->Behavior-->Key to show the HUD

How do we install the HUD?
Add the following development (probably unstable) PPA (Precise)

sudo add-apt-repository ppa:unity-team/hud

sudo apt-get update
sudo apt-get install unity
