I really enjoy using my deck but having the fn key where the right alt key should be is driving me crazy! I use the right alt constanty for work and since I'm working from home now it's becoming a problem
Can the fn key be remapped in some way? I'm already using autohotkey but since the function key doesn't seem to record a press I'm unable to remap it

Any advice anyone?

The only real way to do this is to cut the traces on the PCB and do some fancy wiring. This is not for the faint of heart and would void your warranty but it is possible.
