How to set up Hot Corners?

• Install CompizConfig Settings Manager (ccsm) from the software centre or by issuing command sudo apt-get install compizconfig-settings-manager

• Launch ccsm

• Assign regular actions to corners by editing it's bindings. For example to show and pick from all windows of a current workspace:

• To assign custom action to corner search for the 'commands' plugin. Enable it. In the options for that plugin, you get several lines where you can enter commands, and then in the 'edge bindings' tab, you can set hot corners that will run that command. For instance, you want to launch Firefox by pointing in the top right corner. Enter 'firefox' in 'Command line x', then in 'edge bindings', click on the button marked 'none' for that command, and enable the relevant corner.

• NOTE: 'Button bindings' is also useful, giving you the option to run the command by going to a corner and clicking with the mouse.
