as far as my setup goes, I have a g510s keyboard. I have hotbar 1 (rotating bar) mapped to the "QWERTYUIOP{}"line. hotbar 2 is mapped to the "1234567890-=" line. ASD and X move my menu. my numpad is mapped to character movement, arrow keys are mapped to camera movement. I use bars 1 3 and 4 for my rotations. my g-keys are mapped to access hotbars 5 and 6.

until a recent change, I was using the first 3 spots on hotbar 2 to swap my main hot bar. I haven't fully integrated that change yet with my playing. I mapped the hotbar switch binds over on the keypad which will let me free up those 3 slots.
