Unicode input in QMK works by inputting a sequence of characters to the OS, sort of like a macro. Unfortunately, the way this is done differs for each platform. Specifically, each platform requires a different combination of keys to trigger Unicode input. Therefore, a corresponding input mode has to be set in QMK.
Documentation: Feature Unicode
On this keymap the default unicode mode it's UC_LNX
.
You can change it permanently tapping 2 times the KeyOne to select the next mode.
To add more functionality to this Minimal Keyboard, it's implemented the tap dance feature, so pressing the same key multiples times will produce different emojis.
