Hey Hasu, thanks for the awesome controller! I just received my fc660c controller and it's great!
I'm trying to map C-[ to ESC. So far I have tried mapping ACTION_LAYER_MODS(3, MOD_LCTL) to left control, and Layer 3 [ to ESC, but I think when I press C-[, it triggers C-ESC, which is not exactly what I want. Is there a way to do this?
Thanks again!
edit: One thing I've thought of us to map left control to L3, and map every key on Layer 3 to ACTION_MODS_KEY(MOD_LCTL, KC_1) etc, but that seems very tedious and it seems like there's a better way to do this.
