Whoa, whoa, whoa, there are a whole lot of better ways to do that.
Left stick axes are 8,2,4,6, Right stick axes are 7,9, a, z. Click Left Stick for \, click Right Stick for tab.
X button for Q. LT for Space, RT for Ctrl. D-pad for arrow keys. Y button for toggle Primaries. B button for toggle Secondaries. A button for countermeasures.
Still have two bumpers open? REMAP!
L-bumper, remap targetting/energy keys. LB + A = Target (T). LB + X = Target Hostile (H). LB + Y = Target Friendly (F). LB + B = Target Escort (E). LB + RT = Target Bomb (B). LB + LT = Target Reticle (Y). LB + LDPAD = Energy to Guns. LB + RDPAD = Energy to Engines. LB + UDPAD = Energy to Shields. LB + DDPAD = ummm, equalize energy? That'd be useful.
R-bumper, remap wingman commands. RB + A = Context sensitive universal "Do <x>" command where <x> is either Destroy or Defend, depending on whether target is enemy or friendly. RB + B = Universal Engage Enemy command. RB + X = Cover Me. RB + = Universal Ignore Target command. RB + LT = Call Support. RB + RT = Cancel Support. RB + DPAD = Command menu.
That's, what, 36 discrete commands, with another whole lotta options with a command menu?
Hey look! I got all 16 of your need or die without even remapping, and then some!
I demand you be satisfied with my XBox controller!
