BIGGER SCREEN


Click on f11 to obtain bigger screen size.

Click again on f11 to revert to smaller screen size.

The task bar at bottom of screen might disappear. 
To bring it back just drag the cursor down to the bottom of the screen and beyond.

Taking the cursor to the top of the screen will bring down a toolbar from which you can revert to the original screen.

If F11 does not  bring you to a full screen (This is the case with some of the lesser known browsers), click on VIEW at the top of the screen.
