# a layout for the Mitosis
|
|
|
|
|
|
|
|
- Emphasis on momentary modifiers, all usable from either hand, arranged
|
2018-03-27 16:18:28 +00:00
|
|
|
symmetrically, but distinguishable left/right by the OS. Shift, Red
|
|
|
|
("Lower"), Blue ("Raise"), Super ("Windows"), Meta ("Alt"), Hyper.
|
2017-11-03 15:56:06 +00:00
|
|
|
|
2018-03-27 16:18:28 +00:00
|
|
|
- Red and Blue are used to momentary-enable (like a shift key) one of three layers:
|
2017-11-03 15:56:06 +00:00
|
|
|
|
2018-03-27 16:18:28 +00:00
|
|
|
- Red: Symbols layer
|
|
|
|
- Blue: Numbers layer
|
|
|
|
- "Purple" (both Red and Blue): Functions layer
|
2017-11-03 15:56:06 +00:00
|
|
|
|
2018-03-27 16:18:28 +00:00
|
|
|
- The base layer is QWERTY. A slight variant of [Workman][] may be toggled-on.
|
|
|
|
|
|
|
|
- Emphasis on minimizing hand travel, so as not to lose orientation with
|
|
|
|
homerow.
|
2017-11-03 15:56:06 +00:00
|
|
|
|
|
|
|
- Paired programming symbols (braces, brackets, parentheses) are arranged
|
2018-03-27 16:18:28 +00:00
|
|
|
symmetrically in the symbols layer.
|
|
|
|
|
|
|
|
- `?` and `!` are moved to take the place of `<` and `>`. Rationale: unmodded
|
|
|
|
and shifted keys should be for prose, while symbols useful for programming
|
|
|
|
should be colocated on their own layer.
|
2017-11-03 15:56:06 +00:00
|
|
|
|
|
|
|
- No OS keymap modification required.
|
|
|
|
|
|
|
|
## Design notes
|
|
|
|
|
|
|
|
- **I use an 8Mhz Pro Micro.** If you want to use this keymap with the standard
|
|
|
|
16Mhz Pro Micro specified in the Mitosis design:
|
|
|
|
|
|
|
|
- Remove the lines in `rules.mk` mentioning `F_CPU` and `F_USB`.
|
|
|
|
- Remove the lines in `config.h` mentioning `SERIAL_UART_BAUD`.
|
|
|
|
|
2018-03-27 16:18:28 +00:00
|
|
|
- Workman layout
|
2017-11-03 15:56:06 +00:00
|
|
|
|
2018-03-27 16:18:28 +00:00
|
|
|
- I'm learning a new physical key placement, so I might as well go all out
|
|
|
|
and use an optimal non-QWERTY layout.
|
|
|
|
|
|
|
|
- I like the way Workman feels and some of its advantages over Colemak.
|
|
|
|
Unfortunately, it was designed using a weighting system based on a
|
|
|
|
standard column-staggered keyboard so is probably not as optimal as one
|
|
|
|
could achieve on an ergonomic board like the Mitosis. Maybe run an
|
|
|
|
optimizer routine after I determine good values for key difficulty on the
|
|
|
|
Mitosis.

|
|
|
|
|
|
|
- Arrows in the home position (on a layer). Mod+Arrows = PgUp/PgDn/Home/End,
|
|
|
|
which is intuitive for me
|
|
|
|
|
2018-03-27 16:18:28 +00:00
|
|
|
- I use tab all the time for autocompletion. To allow it to live on the base
|
|
|
|
layer it is now Mod-Tapped with left shift.
|

### Abandoned ideas
|
|
|
|
|
|
|
|
- ~~"Since QWERTY and Workman keep angle brackets together, place other
|
|
|
|
enclosing symbols on the same keys. This informs the numbers placement,
|
|
|
|
which informs the function-key placement."~~
|
|
|
|
|
|
|
|
- I tried this and it was bad. I don't like having to pick the right
|
|
|
|
modifier to get the right flavor of bracket. Instead, now, one modifier
|
|
|
|
activates a symbols layer where all brackets are easily accessible.
|
|
|
|
|
|
|
|
- Space/Enter to the left of layer select for Enter doesn't work well; I always
|
2018-03-27 16:18:28 +00:00
|
|
|
trigger space first when mashing the keys simultaneously. This might not
|
|
|
|
continue to be true if I change the angle at which I strike the keys e.g.
|
|
|
|
with a neoprene base or a wrist support.

|
|
|
|
2018-03-27 16:18:28 +00:00
|
|
|
- I used to have Blue on ring finger, but that was too hard to use in
|
2017-11-03 15:56:06 +00:00
|
|
|
conjunction with shift.
|
|
|
|
|
|
|
|
## To do
|
|
|
|
|
2018-03-27 16:18:28 +00:00
|
|
|
- Figure out where to place non-numpad numbers so we don't need num lock turned
|
|
|
|
on to type them?
|
2017-11-03 15:56:06 +00:00
|
|
|
- Improve LED indications (may require modding bluetooth firmware):
|
|
|
|
- Is any board nonresponsive (which one?)
|
|
|
|
- Does either board have a low battery?
|
|
|
|
- Add Insert, PrintScr, Pause/Break
|
2018-03-27 16:18:28 +00:00
|
|
|
- ~~Make QWERTY base layer for people who customize layout in software?~~ I
|
|
|
|
default to QWERTY now.
|
|
|
|
- Store default base layer in eeprom?
|
|
|
|
- See if the henkan/muhenkan placement is at all useful for Japanese speakers,
|
|
|
|
or abuse different keysyms for Left/Right Hyper. (Original space cadet used
|
|
|
|
scancodes 145/175. 145 is LANG2, 175 is "reserved" in USB HID spec.)
|
|
|
|
- Mod a buzzer onto my receiver and enable tones
|
2017-11-03 15:56:06 +00:00
|
|
|
- Implement "layer lock" key
|
|
|
|
- Improve tri-layer behavior
