right know i'm using a solaris keyboard and they have a lot of extra ones (no any key though). there are the unix ones such as meta and alt and stuff. then there's an alt graph key, compose, help, stop, props, front, open, find, aagain, undo, copy, paste, cut. there are 4 keys in the upper right 3 of which control the monitor's brightness or the speaker volume. the fourth has a crescent on it, i don't know what its for. there's also a blank key with no letters or symbols on it.
