What I did was super simple, I hardly feel it's worth posting. I just set the keys 1-9 on the master to broadcast keys 1-9 on the slave and put similar macros on the hotbar for each number (like 1 is initiate attack/debuff on both, another key is heal target/heal self... etc) and added a keystroke to toggle hotkeys on and off. I still use a mouse for the second box but can probably eliminate that.

I'll be playing with more options later, thats all I had the patience for before playing. Going to try and incorporate the mouseclick feature and figure out what I'd like to do with the other buttons on my G5 mouse.

It's a pretty cool program. Unfortunately most of the sample scripts are for wow and there are commands which will not work with EQ2.
