I've dug my old 400 DV SE out of mothballs to use to transfer video tapes with an eyetv box. I've upped the memory to 1GB, tossed the hockey puck and so far so good... but I can't remember the uses of the function keys on this old keyboard (2452). I don't really need them, but now my curiosity is piqued. I'm running Tiger. Anyone know what the fkeys do?
