I discovered, quite accidentally, an interesting feature in Windows 7.  Aero Shake.

Basically you can grab any window in windows 7 by the title bar – the bar along the top of the window – with your mouse and shake it backwards and forwards, and it will minimise all the other windows you have open.  If you shake the window again, the minimised windows will pop back up. For any keyboard junkies – you can achieve the same effect with Windows Key + Home.

This can be really useful if you want to clear out the clutter of all of your windows and focus on one thing for a while.

This feature is included in the Home Premium, Professional, Ultimate, and Enterprise editions of Windows 7.  Click this link if you want to find out more and see a video of Aero Shake in action.
