Moonlander Keyboard Off Button (Sort of)

I wanted to be able to turn my ZSA Moonlander keyboard off, so my cat wouldn't press keys when walking on it. But there is no dedicated "off" button on the keyboard. My workaround was creating a layer where all the keys were "null" except one. On my main layer, I made double-tapping a certain key switch the keyboard to the null layer. Then, double-tapping that same key switches back to the main layer. I used double tap because a cat is highly unlikely to press the same key twice rapidly.

The off button has the added convenience of turning the lights off. I know one can program a lights-off command, but I like turning the keys and lights off in one easy command.

I'd love the ability for the keyboard to shut off after a selected amount of time with no activity. Perhaps ZSA will add that feature one day.
