Use your G15 profiler ( Black g15 icon in your taskbar) assign all your keys to hotkeys

For example
alt1 through alt10
num1 through num10

Just wierd combos that will not conflict with the rest of the keyboard.
Download the wow g15 addon found at curse.com

Go into your keybinds inside wow and find the subsection for the g15 addon, and start assigning keys (It is layed out wierd in there but a little play around and you will get it.)

And there you have it my friend, i think a proper write up must be made one day but my busy schedule does not allow :P.
