This keymap attempts to match the Kinesis Contoured (aka Advantage) default
layout as closely as possible. See
http://www.kinesis-ergo.com/wp-content/uploads/2013/06/advantage_layout_win.pdf
Apart from the obvious mappings, this keymap also:
* removes the dual-purpose momentary layer/normal keys: Z, /, and Grv;
because the author--coming from a Kinesis keyboard--finds the delays and
accidental modifiers to be more disconcerting than helpful.
* puts Esc in the bottom left since there's no place for it in the top
left to match the Kinesis.
* changes the bottom-right key into an L2 toggle since there's otherwise no
way to get to L2.
* adds PrScr, ScrLk and Pause to the L1 keymap, down the left side, since
they're present on the Kinesis but not available in the default
ergodox_ez keymap.
This moves the keys closer to a traditional layout with some redundancy
around the middle to compensate for fast non-traditional typists like
myself who tend to wander from the home row a fair bit. Navigation keys
are provided in layer 2 (accessed by left thumb button), programming
symbols and classic numeric keypad in layer 1 (accessed by right thumb
button). Permanent layer switching is provided with a smaller thumb
button. Ctrl provided in place of caps lock (because no-one needs
caps/num lock), space, backspace, enter, shift all in traditional
positions with layer 1 providing things like equals, tilde and
apostrophe (an attempt to re-use existing muscle memory).
LEDs are pimped to the point of being silly (fading in/out on layer
switch, rolling on reboot ... because I can). Power and reset keys
provided on left thumb pad in layer 2.
No meh or hyper as I haven't found a burning need for them yet.
