Every now and then when I'm using Excel 2003, my arrow keys will start
moving the frame around (as if I were scrolling) instead of moving
between cells. Is that because my scroll lock is on?

There is no light indicating if the scroll lock is on - I mean, there
is no such light on my laptop at all. Is there any way to tell within
Excel or on my PC?
