Screen Refresh

Do you know how to refresh your screen with out taking the mouse and clicking on the refresh button? Well a friend pointed this out to me today. Instead of grabbing that mouse while your typing away just press the F5 Key and your screen will refresh. Neat trick and I know it works with IE7 I am not sure about prior versions or Firefox. So if anyone out there wants to leave a comment and try this feature out with any of the other browsers. Leave a comment if it works in the other browsers.
