Miryoku is an ergonomic, minimal, orthogonal, and universal keyboard layout.
This document describes miryoku for ZMK only. For the development branch, general documentation, and other implementations see github.com/manna-harbour/miryoku.

Layout
Layers
The layers are maintained in tables, with the thumb keys on the bottom row.
X_NP indicates the key is not present and is used to fill in the table around
the thumb keys. The grid arrangement of the tables does not imply a particular
physical layout.
Basic keycodes are entered without the KC_ prefix. Symbols can be entered
as-is, except for '-' (MINS), '.' (DOT), '|' (PIPE), and '"' (DQUO).
Empty cells are unused.
The base layer has both halves of the layout joined for convenience. Other layers are specified as a single hand.
Base (BASE)
The base layer is maintained as separate tap and hold tables and are combined into the corresponding tap-hold keycodes for mods and layer change. Mods (and reset) will be available on sub layers on the same hand as the layer change thumb key. Unknown names are considered to be layer names.
Base layer alphas are Colemak-DHm. Thumb keys are backspace, enter, delete on the right and space, tab, escape on the left. Dot, comma and apostrophe are included for prose, dot and slash for file and directory names.

Navigation (NAVR)
Primary right-hand layer (left home thumb) is navigation and editing. Cursor keys are on the home position, line and page movement below, clipboard above, caps lock and insert on the inner column. Thumb keys are duplicated from the base layer to avoid having to layer change mid edit and to enable auto-repeat.
| AGIN | UNDO | CUT | COPY | PSTE |
| CAPS | LEFT | DOWN | UP | RGHT |

| ENT | BSPC | DEL | X_NP | X_NP |
Mouse (MOUR)
Secondary right-hand layer is mouse emulation. Mouse movement mirrors cursor navigation on home and wheel mirrors line / page movement below. Buttons are on the thumbs (L, M, R). Mouse movement, click, and drag with modifiers can be performed from the home position. Unused keys are available for other related functions.

Mouse Buttons Overlay (MBO)
Available for automatic activation depending on keyboard hardware and configuration. Not activated manually.
| X_NP | X_NP | BTN1 | BTN3 | BTN2 | X_NP | X_NP |
Media (MEDR)
Tertiary right-hand layer is media control, with volume up / down and next / prev mirroring the navigation keys. Pause, stop and mute are on thumbs. RGB control is on the top row (combine with shift to invert). Unused keys are available for other related functions.

| MPRV | VOLD | VOLU | MNXT | |
| MSTP | MPLY | MUTE | X_NP | X_NP |
Numerals and Symbols (NSL)
Primary left-hand layer (right home thumb) is numerals and symbols. Numerals are in the standard numpad locations with symbols in the remaining positions. Dot is duplicated from the base layer.

| ; | 4 | 5 | 6 | = |
| ` | 1 | 2 | 3 | \ |
| X_NP | X_NP | DOT | 0 | MINS |
Shifted Numerals and Symbols (NSSL)
Secondary left-hand layer has shifted symbols in the same locations to reduce chording when using mods with shifted symbols. Open parenthesis is duplicated next to close parenthesis.
| { | & | * | ( | } |
| : | $ | % | ^ | + |
| ~ | ! | @ | # | PIPE |
| X_NP | X_NP | ( | ) | _ |
Function and System (FUNL)
Tertiary left-hand layer has function keys mirroring the numerals on the primary layer with extras on the pinkie column, plus system keys on the inner column. App (menu) is on the tertiary thumb key and other thumb keys are duplicated from the base layer to enable auto-repeat.

Alternative Layouts
The defaults are recommended, but alternative layouts are provided to accommodate existing muscle memory.

Subset Mapping
The keymap, build options, and configuration are shared between keyboards. The layout is mapped onto keyboards with different physical layouts as a subset.
