Add a chord that stops all keybord signals being sent to the host until it is pressed again. Usefull for putting on your coat or other times when you don’t want stray keys sent.
Currently I (Greg) do this with a seporate switch that disconnects the ground line to the chorder’s keys. An On/Off chord would eliminate this switch. However it would also introduce some uncertanty unless perhaps it was combined with the an LED signal. Perhaps slow flash? Or mabey one signal for entry into “Off state” and a different one for exit from “Off state”?
