[Keymap] New kbd67/hotswap keymap for writing both code and math (#4933)
* Custom keymap. * Fix magic layer, enable Unicode. * Update README. * Make Unicode config change keymap-local. * Move magic to AltGr, simplifying layout. * Changes per Drashna. * Fix magic+esc = backtick! * Change reset implementation per Drashna's suggestion. * Add a few more symbols so long as the commit is open - √ℜℂℤ⊙ℚℕ and the like. * Typo fix. * Slight simplification, drop an extra variable.master

* Custom keymap for kbd67, for those who need to both code and type math.
|
||||||
|
* Author: Yonatan Zunger (zunger@gmail.com)
|
||||||
|
|
||||||
|
This keymap is presently rather Mac-centric, as it uses Mac media keys in its function layer and the
|
||||||
|
OS X Unicode input mode for the "magic" layers.
|
||||||
|
|
||||||
|
*Layer 0 (Base QWERTY):* The layout has a few minor quirks: grave escape, Home/End/PgUp/PgDn in the
|
||||||
|
right-hand column (rather than the more common Home/PgUp/PgDn/End), and a pause key between
|
||||||
|
backspace and home -- this being something I use for screen lock, a necessity when one works with
|
||||||
|
and sits next to security engineers. (Using a heavier switch on the pause key greatly reduces the
|
||||||
|
risk of accidental triggering) In OS X style, alt and win are swapped on the left-hand side.
|
||||||
|
|
||||||
|
The right-hand alt and gui keys take on a different meaning: right-alt lives up to its old name of
|
||||||
|
AltGr by invoking Greek (the "magic" layers, 2 and 3), and right-gui invokes the function layer.
|
||||||
|
|
||||||
|
*Layer 1 (Functions):* This layer deliberately sets KC_NO for the keys it doesn't use. I realize
|
||||||
|
this isn't common, but I like to keep my functions quite distinct from all other layers.
|
||||||
|
|
||||||
|
RESET can be accessed at Fn+Left Shift+Escape.
|
||||||
|
|
||||||
|
*Layers 2 and 3*: These are invoked by the "magic" key (AltGr) and by magic+shift. The
|
||||||
|
letters mostly produce Greek; the numbers, superscripts (magic) and subscripts (magic+shift); and
|
||||||
|
the various other keys, mathematical symbols. There unfortunately aren't nearly enough keys for all
|
||||||
|
the symbols I'd like, so magic+alt and magic+alt+shift may end up existing as well, giving this a
|
||||||
|
proper Space Cadet effect; but that said, it's going to be hard to remember where all these symbols
|
||||||
|
are without some extremely custom keycaps. In the limit of arbitrarily complex layers, the keyboard
|
||||||
|
will probably start running LISP and turn into EMACS.
