Quickly switch to the desktop

I realised how much efficiency I have gained through Windows 7 using the Aero Peek or bottom right hand button that shows desktop as well as learning the Windows + D shortcut to switch to the desktop.

A recent modification I made was to go into the mouse settings and assign the middle click button to show desktop, now I can quickly switch applications, open apps or files and folders in 1 click and 1 click to bring back the last program I was using. Its pretty quick and easy, like in games to switch between modes or screens but it will disable the open in now window function which really only works in Internet browsers.

EDIT/Fix: You can add program specific settings and add Firefox to it and allow the middle click button to be Middle Click rather then Show/Hide desktop.
