Extra dedicated multimedia/programmable keyboard?

Hi,

I'm after a device that I'm sure must exist, but I can't find. Something like a dedicated numberpad keyboard, but for multimedia/hotkey assignment.

Essentially I want to map a load of hot-key functions (cmd/+, cmd/-, cmd/shift/s etc) to a dedicated device (I'd imagine they might exist for gaming if not multimedia?).

Any ideas of somewhere (especially in the UK) that would sell such a device? I've had a quick look around ebuyer, and amazon, but can't find anything ... but also don't really know what to search for without just finding multimedia keyboards etc.

Thanks in advance,

p.s. I just came across the logitech gamingboard ... I'm after that kind of thing, but much more basic ... I don't need a HUD or madly complicated structure, just a pad with a dozen or so function keys on it.
