Question: Is it possible to remap keys by changing a bit of code

[LukasPietzschmann]

I recently installed this driver and it has been a awesome experience so far (so thanks a lot for all your work on this!). But some keys are swapped, no matter what keyboard layout I choose. So I wanted to look into the code of this driver and find out if it is possible to remap the swapped keys. But I did not find the right place to do modifications to. Can anyone point me to the correct file / location where remapping keys could be possible? Thanks in advance :)
