Addon to assign multiple keys to a direction?

G15!

hmm.. that's a good idea.. i might just do that, u rock

I'd be careful there, was the reson I asked about an addon. Using the G15 to do this in any manner than telling it to push 2 keys at once (eg shift down, o down, p down, p up, o up, shift up) would be bannable. The issue comes about that it would be possible to do any two of these combinations within the WoW UI as it currently stands, but to be able to do all 4 requires something else and I'm hoping there is something legel to do it, otherwise I'll stick with just using two of them.
