Lion Tip : How to Quickly Force Quit the Current Active Application

Have you ever accidentally clicked on an application in the Dock or had an application hang and need to force quit the application quickly?
Hold down the Command+Alt+Shift+Escape keys together for a couple of seconds to force quit the currently active application without the usual confirmation dialog shown below. Please be aware though that there will be no warning at all, the currently active application will quit immediately and therefore there is the risk of losing unsaved changes!
Don’t forget you can use the Command+Alt+Escape keys to access the Force Quit window shown below to allow you to manually select which Application to force quit.
This feature has been tested using Mac OS X v10.7.4 which was the latest Mac OS release at the time of writing and also using the latest Internal and external Apple keyboards.
