wow, the scroll bar is the part of the screen you use to make what's on the screen go up or down. It's likely on the very edge of one side (the right, on mine), with a square that has a triangle in it at either end, and a moveable rectangle that you can slide up and down it. If what's on your screen is w-i-d-e, you'll have one across the bottom, too, to move things right or left. Now, if someone would tell me what that bottom bar where Start, etc., is called, I'd appreciate it.
