/* Features of this keymap:

--Lots of functionality on left hand for conjunction with mouse or pen in right hand
--_COMMAND layer ESDF arrow keys
--_MEH layer ESDF is super handy for switching tabs (SF) and apps (ED)
--_MEH layer other keys are linked with my AutoHotKey script
--macro for handling parentheses is very nice (credit: u/drashna)

Some things are very non-standard, like position of number keys, etc.
Will require heavy modification for most people.
