Does anyone know if it is possible to have keycaps that show a different legend based on the color of the switch led?
So if I change to layer 1 and all the switch LEDs turn red, then a specific set of icons appear on the keys. And, if I go to layer 2 with green LEDs, it shows different icons…
I am guessing that it would involve some sort of color filter screen embedded into the keycap to only allow specific light waves through in different shapes?
Does that exist already?
