If you use Windows 7, you might like this one. To make any page you are looking at move to fill the screen (if it is not already full screen), just hit the 'Windows" key and the "up arrow" key. If you want the open window to fill half the screen and move to the left side, hit the "Windows" key and the "left arrow" key. To move right, Windows and right arrow. Hit the same combo to go back to where you were.
