This is a configuration with prioritized navigation keys (arrows and such): LINK
Inspired by the thumbless conf, the pinky is responsible for shift and ctrl.
The thumb mostly rests on Num and Alt.
Numbers 1 to 9 are mapped in dialpad fashshion with Num modifier.
This initial basic configuration maps the letters y, z, x, c, v, f for undo-redo, copy-paste and find operations in combination with ctrl. Also | , - ' are mapped so that one could start creating configuration for twiddler using twiddler.
To quickly add a new letter binding in .cfg.chords plaintext file, press MOOM aka. -||- in 4finger notation. Then open this file in Twidlit.jar and "Save As CFG" to get the twiddler.cfg. Mapping of keys works correctly for English keyboard layout.
