Center Torso - X (because Z,X and C in this mapping are all movement related controls, and X happens to be in the middle)
Full Stop - C
Toggle Power - LCtrl (a button a bit further away from main controls so you won't hit it by accident)
Next Target - Q (a frequently used button, which should be placed somewhere very convenient. and because I like Battlefield)
Show Target Overlay - T (seriously, people rarely use that button until late game checking teammates' status. and its the initial letter.)
Free Look - LAlt (who use that?)
Override Shutdown - Z (a conveniently located button to spam)
Weapon Door Toggle - F (why not)
Toggle Zoom Mode - E (very convenient)
Adv. Zoom - R (close to normal Zoom)
