space space default layout

Default layout on space space uses 3 layers + base, 5 combos, layer taps on the split space bars, and tap-hold for shift on F & J.

* combos include:

O+P = backspace

K+L = enter

S+D = tab

T+Y = escape

Q+W = delete


* The encoders are also set to function differently depending on layer:

right encoder
default = volume up/down

symbol layer (hold space) = media next/previous

left encoder
default = mousewheel up/down

number layer (hold backspace) = page up/down

nav layer (hold Fn) = control tab/control shift tab

Default Layout:
