How many keyboard shortcuts for Shotwell, Rhythmbox or LibreOffice do you know? If you're anything like me (i.e. a slave to the mouse) then the chances are not many.

How many of Unity's keyboard shortcuts do you know? Probably not as many as you'd like!

The overlay presents a handy list of key-combos for accessing and navigating various Unity features - which are ideal for power users.
