Change Axis lock binding from arrow to say 'Z' key?


I would like to change the locking axis specifically for the Z axis because I use it often and having to move my hand across my keyboard from ASDF position is extremely cumbersome.

Holding down [Shift] is near ASDF. Is that an option to temporarily lock to Z when the blue axis turns up?

If you have a Logitech mouse or any mouse with extra buttons you could assign a button to be the up key.
