You can write special lessons with great ease. Qwerty, Dvorak, left handed Dvorak, right handed Dvorak, or any other keyboard lessons can be written in a few minutes. Write lessons with legal words. Don't like my lessons. A typing tutor should start with the home keys.
Different keyboards have different home keys.
Home keys are introduced first. Nearby keys are next. Different keyboards need different tutor lessons. Of course not. I learned on a Qwerty tutor.
