Why didn't someone tell me that keymaps were the answer to my formation issues? Now my 2nd clone can have his DOWN arrow back instead of having it mapped to Z!!

Just to clarify (i'm at work and bored) - I can map Z to DOWN arrow on clone 1, left on clone 2, right on clone 3?

Is it possible to do 2 keys simultaniously (not A then B, I mean AB)? or for example - DOWN arrow and LEFT?
