Usage

Goal is to use caps lock button functionally as control + escape

escape on tapping for usage in vim like applications

control to be used when using key combinations e.g ctrl a in tmux

Mapping

left control -> on tap = Esc

left ctrl -> on hold + hjkl = left, up, down, right arrow keys

change positions of control and caps lock: re-map caps lock key position to left control re-map left control key position to CAPS lock key
