ScrollLock, though... what a pointless key.
I do use scrolllock. Not because it does something in an application - but because I've some hardware that uses it: my switchbox. <<ScrollLock>><<ScrollLock>><<Page-Up>> goes to the next active computer, <<ScrollLock>><<ScrollLock>><<Page-Down>> goes to the previous active computer. There are a few more commands using scrolllock, but I can never remember them.
