I understand how a dead key works, that's how I type ñ currently, pressing the dead key and later pressing n. I use the Dvorak international layout, but if I used the English QWERTY it would be the same.
I think maybe the problem is that the Mod keys don't work on Mac. I checked and saw that to install the Neo keyboard it tells you that to activate the Mod keys you have to install the program Karabiner elements, which I wouldn't do. Maybe the same happens with ADNW.
When I type Mod3, which is Caps Lock, the letter keys all change to
Capital letter but they change the letter, like, this is the layout that
I get:
XVÜCWKHGFQ?´
HIEAOSTRTDẞ
XÖÄPQBM;:J
As you can see on the homerow I the letter T appears twice.
Maybe someone else here uses ADNW on Mac?
Thank you
