It should show you the key on your actual layout (so Turkish-Q in your case).
If I understand correctly, then the experimental keyboard mapping function seems to be quite reliable.
Yes, that’s expected and can be ignored. It wouldn’t do that in the actual implementation. Also see the TODO part I put into the code at the very bottom.
I didn’t look into combining it with Shift, Alt, ect yet. So that’s expected.
Not sure if tommylenz or someone else here is going to try 3rd party keyboard libs in the future – if not, then I’ll probably be able to test it in about 8-12 weeks.
