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, Red
9 ("Lower"), Blue ("Raise"), Super ("Windows"), Meta ("Alt"), Hyper.
11 - Red and Blue are used to momentary-enable (like a shift key) one of three layers:
15 - "Purple" (both Red and Blue): Functions layer
17 - The base layer is QWERTY. A slight variant of [Workman][] may be toggled-on.
19 - Emphasis on minimizing hand travel, so as not to lose orientation with
22 - Paired programming symbols (braces, brackets, parentheses) are arranged
23 symmetrically in the symbols layer.
25 - `?` and `!` are moved to take the place of `<` and `>`. Rationale: unmodded
26 and shifted keys should be for prose, while symbols useful for programming
27 should be colocated on their own layer.
29 - No OS keymap modification required.
33 - **I use an 8Mhz Pro Micro.** If you want to use this keymap with the standard
34 16Mhz Pro Micro specified in the Mitosis design:
36 - Remove the lines in `rules.mk` mentioning `F_CPU` and `F_USB`.
37 - Remove the lines in `config.h` mentioning `SERIAL_UART_BAUD`.
41 - I'm learning a new physical key placement, so I might as well go all out
42 and use an optimal non-QWERTY layout.
44 - I like the way Workman feels and some of its advantages over Colemak.
45 Unfortunately, it was designed using a weighting system based on a
46 standard column-staggered keyboard so is probably not as optimal as one
47 could achieve on an ergonomic board like the Mitosis. Maybe run an
48 optimizer routine after I determine good values for key difficulty on the
51 - Arrows in the home position (on a layer). Mod+Arrows = PgUp/PgDn/Home/End,
52 which is intuitive for me
54 - I use tab all the time for autocompletion. To allow it to live on the base
55 layer it is now Mod-Tapped with left shift.
59 - ~~"Since QWERTY and Workman keep angle brackets together, place other
60 enclosing symbols on the same keys. This informs the numbers placement,
61 which informs the function-key placement."~~
63 - I tried this and it was bad. I don't like having to pick the right
64 modifier to get the right flavor of bracket. Instead, now, one modifier
65 activates a symbols layer where all brackets are easily accessible.
67 - Space/Enter to the left of layer select for Enter doesn't work well; I always
68 trigger space first when mashing the keys simultaneously. This might not
69 continue to be true if I change the angle at which I strike the keys e.g.
70 with a neoprene base or a wrist support.
72 - I used to have Blue on ring finger, but that was too hard to use in
73 conjunction with shift.
77 - Figure out where to place non-numpad numbers so we don't need num lock turned
79 - Improve LED indications (may require modding bluetooth firmware):
80 - Is any board nonresponsive (which one?)
81 - Does either board have a low battery?
82 - Add Insert, PrintScr, Pause/Break
83 - ~~Make QWERTY base layer for people who customize layout in software?~~ I
84 default to QWERTY now.
85 - Store default base layer in eeprom?
86 - See if the henkan/muhenkan placement is at all useful for Japanese speakers,
87 or abuse different keysyms for Left/Right Hyper. (Original space cadet used
88 scancodes 145/175. 145 is LANG2, 175 is "reserved" in USB HID spec.)
89 - Mod a buzzer onto my receiver and enable tones
90 - Implement "layer lock" key
91 - Improve tri-layer behavior
