Does anyone know if there is a list of the default variable names used for text substitution referenced here:
https://docs.kicad.org/6.0/en/pcbnew/pcbnew.html#board_setup
I know some variable names including REFERENCE, VALUE and that user defined field names can be used as well as text variables defined in the board settings. The question is are there any other system defined variables and if so, is there a list of them somewhere?
