I want to change the firmware of my keyboard such that I have two customised layouts in it. This means, I would have layers PRIMARY_A and PRIMARY_B, but also FUNCTION_A and FUNCTION_B, NumPad_A and NumPad_B and maybe WEIRD_STUFF_A. Basically, two unrelated groups of layouts.
I now wonder what the best way to change between them would be. I thought I would dedicate a key somehow (e.g. FN+Prog) to change the currently active layout group. Unfortunately, I cannot figure out how the firmware keeps track of which firmware it is in, currently. I suspect that LockLayer is not the right tool. I would have LockLayer in each group too, e.g. to reach NumPad.
Can anyone help me out here?
