How to reassign keys used to enter notes

HARD CODED! Incredible. Seems like it wouldn’t take much to recify.

In the tutorial:

… it’s even mentioned that Z may not be in the same position on different keyboards, so I just assumed that there was an easy way to compensate for these types of problems without invoking autohotkey or something.

Has anyone got a workaround? Maybe involving Autohotkey?
