Is it possible to change the shortcut keys?

I need a lot of angle measurements, Positioning the crosshair at the mouse position by pressing Ctrl+Shift+(1,2,3) is a great feature. But my fingers are short and it's too hard to press keys, LOL, Is it possible to change the shortcut key to Ctrl+shift+(z, x, c). One more suggestion is whether the angle value can be increased (180 - angle = angle value). Thank you very much for the software you developed, it helped me a lot.

Thanks @linhaiqd for the requests. I split this into two separate enhancement request (this for the shortcut keys and #23 for the angle).
