This is the very simple layout I use for my Twiddler 3.
It's different in a few ways:
- I sacrifice chord count in favor of using only one column for most chords. I find it more comfortable.
- I don't rely on the thumb buttons for any chords, so I can use my thumb to grip the Twiddler
- The alphabet counts up in binary. This makes it a lot easier for me to learn.I'm using a layout that counts the letters
