I'm using the colemak layer -- customized a bit to work a bit better when using spacemacs as my editor.
SC1
=> LGUI + TAB
SC2
=> LGUI + SPACE + TAB
L1
=> Switch to QWERTY Layout
T(L2)
=> Toggle Symbol Layer
T(L3)
=> Toggle Number and D-Pad Layer
Nothing special here -- just need this layer tucked away for the WASD
. Which is literally the only reason I use it.
Just have the same button to toggle back to colemak.
This is just putting matching closing symbols next to each other -- useful when editing lisp.
Just a basic number layer with a D-PAD on the other side.
