I also decided to change all calls to `persistant_default_layer_set()` to

## Base Layers (Qwerty/Colemak/Dvorak)
These base layers are mostly the same as the default mappings. The interesting
as the modifier, with the `IJKL` home row keys representing the inverted-T of
the arrow keys. All of the default TouchCursor keymappings for the right hand
are represented below. My personalizations include all of the keys shown for
-the left hand. Having the `Alt` and `Shift` keys readily accessible from the
-home row allows quick word jumps and highlighting when used in conjunction with
-the arrow keys. The `KC_UNDO, KC_CUT, KC_COPY, KC_PASTE, KC_FIND,` and
-`KC_AGAIN` keycodes have been mapped but they don't seem to work on Mac.
-Presumably they'll work under Windows.
