Movement question with G13 keyboard

Hi all,
so in DTK I had to move my toons due to the holes buff in the first corridor. I setup my G13 and ISboxer that with control pressed on the G13 and then the regular movement key strokes being sent via buttons 2,3,4, 9 (my G13 is assigned 1 - 9 on the first rows and continuing on the second row so with the key pressed above you end up with pretty much the regular movement keypress layout)
How is anyone else using the G13 to better effect for moving your toons? The above seemed very cumbersome (even though it worked) and meant moving stops my dps rotations.
I am thinking maybe have the control key linked to my joystick on the G13 to modify it from moving group vs normally moving my main toon.
any insight?
