Scroll Lock
Running MS Excell 2004, a green light is on next to SCRL at the bottom of the page, and the arrow keys scroll the screen instead of moving between cells. On a PC (sorry, recent convert from the darkside), there's a Scroll Lock key on the keyboard which toggles this on and off. How do i do it on my Mac Book?
