Complete List of Compiz Keyboard Shortcuts

Compiz is one of the most important reason why many love Linux. Compiz is definately the best looking thing on a PC, even Mac OSX looks pale in comparision against Compiz. Ubuntu has included Compiz by default since Gutsy Gibbon (7.10) release. Many of you must have been disappointed to find out that the 'Cube' and other cool effects you saw in the Youtube videos is not present in Ubuntu. Well, don't worry Ubuntu has all the goodies installed you merely have to unlock them. For that you require an amazing utility called “Compiz setting manager”. It gives you an easy to use dashboard for controlling the Compiz effects. Make sure you have the necessary Graphics card available, I'd recommend EnvyNG for that.

Now:

1. Open a terminal window.

2. Execute the following command:
sudo aptitude install compizconfig-settings-manager

To open the Settings Manager, click System, mouseover Preferences and select Advanced Desktop Effects Settings. You will be presented with a large selection of effects to choose from.

Here are the shortcuts.
