I am looking for suggestions on how to lay out my keys
Which XKeys model do you have? I'm guessing the pro since you mentioned double keys.

Personally, I use it just to off-load my healing, whereas others use it to offload pretty much all of their keyboard functions. It's really helpful to have an idea of what you want to do with it, because that may limit how many double keys you can use apart from anything else.

I started with a whole LOAD of double keys and even a couple of quad keys, but soon ran out of space. I don't bind keystrokes to mine either - I use full text macros, but that would only work properly if you're not broadcasting to all machines (my XKeys is connected to a drone machine that doesn't transmit).

Anyway, this is what mine looks like today (complete with ghetto icons, printed on my laser printer and raggedly cut by my own fair hand ) As I said, it's a pure healer (priest healer, specifically) setup.
