Panic button

How do I activate the panic button feature?

Seriously? I never knew we had one.

Set your homepage as something boring, when you don't want what your looking at seen hit the home button on your browser.

For Windows the quickest way I know of is to hold down the Windows key on the keyboard and then press the M key. That will instantly minimize all open windows.

I have a multi-button mouse which you can assign different functions for different buttons. I set the thumb button as close window. Works like a champ.
