Scroll Lock
What the hell does the Scroll Lock key do? And how has it made it onto keyboards all around the world? From what I can tell, the only thing it does is turn that green light in the corner on and off.
I did a little research and learned that virtually no programs use this key anymore - probably because most programs don't run in freaking DOS anymore. It's a holdout from the past that has lost it's relevance in today's world. But for some reason, still gets forced upon us. Kinda like David Hasselhoff.
I vote that this key be removed to save the valuable 1 square-centimeter real estate it occupies. But then again, who knows? Maybe I'll suddenly have to urge to draw a triangle on a sheet of paper using the LOGO Turtle.
