5 # a layout for the Mitosis
7 - Emphasis on momentary modifiers, all usable from either hand, arranged
8 symmetrically, but distinguishable left/right by the OS. Shift, Fn1
9 ("Lower"), Fn2 ("Raise"), Super ("Windows"), Meta ("Alt"), Hyper.
11 - Fn1 and Fn2 are used to momentary-enable (like a shift key) one of three layers:
13 - Fn1 (Red): Symbols layer
14 - Fn2 (Blue): Numbers layer
15 - Both: Functions layer
17 - The base layer is a slight variant of [Workman][]. QWERTY may be toggled-on.
19 - Paired programming symbols (braces, brackets, parentheses) are arranged
20 symmetrically in the symbols layer. `?` and `!` are moved to take the place
23 - No OS keymap modification required.
27 - **I use an 8Mhz Pro Micro.** If you want to use this keymap with the standard
28 16Mhz Pro Micro specified in the Mitosis design:
30 - Remove the lines in `rules.mk` mentioning `F_CPU` and `F_USB`.
31 - Remove the lines in `config.h` mentioning `SERIAL_UART_BAUD`.
33 - I'm learning a new key placement, so might as well go all out and use an
34 optimal non-QWERTY layout.
36 - I like the way Workman feels and some of its advantages over Colemak.
37 Unfortunately, it was designed using a weighting system based on a standard
38 column-staggered keyboard so is probably not as optimal as one could achieve
39 on an ergonomic board like the Mitosis.
41 - Arrows in the home position (on a layer). Mod+Arrows = PgUp/PgDn/Home/End,
42 which is intuitive for me
46 - ~~"Since QWERTY and Workman keep angle brackets together, place other
47 enclosing symbols on the same keys. This informs the numbers placement,
48 which informs the function-key placement."~~
50 - I tried this and it was bad. I don't like having to pick the right
51 modifier to get the right flavor of bracket. Instead, now, one modifier
52 activates a symbols layer where all brackets are easily accessible.
54 - Space/Enter to the left of layer select for Enter doesn't work well; I always
57 - I used to have Blue layer on ring finger, but that was too hard to use in
58 conjunction with shift.
62 - Improve LED indications (may require modding bluetooth firmware):
63 - Is any board nonresponsive (which one?)
64 - Does either board have a low battery?
65 - Add Insert, PrintScr, Pause/Break
66 - Make QWERTY base layer for people who customize layout in software? Store
67 default base layer in eeprom?
68 - See if the henkans placement is at all useful for Japanese speakers, or abuse
70 - Mod a speaker onto my receiver and enable tones
71 - Implement "layer lock" key
72 - Improve tri-layer behavior
