miryoku.org

The miryoku layout is an ergonomic, minimal, orthogonal layout for ergo or ortho keyboards, implemented as part of the QMK firmware. The layout is maintained in emacs org-mode tables and converted to QMK keymap data structures using embedded python scripts. The layout is mapped onto keyboards with different physical layouts as a subset without code duplication using the QMK userland feature and C macros. Versions of the layout can also be seen outside of the QMK source at https://github.com/manna-harbour/miryoku/.

Layout

Info

General Principles

  • Use layers instead of reaching.
  • Use both hands instead of contortions.
  • Use the home positions as much as possible.
  • Make full use of the thumbs.
  • Avoid unnecessary complication.

Specifics

  • 5 columns, 3 rows, 3 thumb keys, 2 hands.
  • Can be used on almost any split or non-split ergo or ortho keyboard.
  • Includes all keys found on a US layout TKL keyboard, plus media keys and mouse emulation.
  • Home row is the middle row, home thumb key is the middle thumb key.
  • Maximum 1-u movement from home position for fingers and thumbs, and only along one axis (except for the inner index finger column which is deprioritised compared with the home columns).
  • Dual-function modifiers on home row, mirrored on both hands.
  • Dual-function layer change on thumbs.
  • Layers are designed orthogonally with a single purpose per hand and are accessed by holding a thumb key on the opposite hand.
  • Holding layer change and modifiers on one hand combined with a single key press on the other hand can produce any combination of modifiers and single keys without any finger contortions.
  • Single function mods are also defined on layers on the same hand as the layer change thumb key so layer change and mods can be held in any order or simultaneously without race conditions.
  • As mods are only enabled on the opposite hand, auto-repeat is available on the home row on layers for use with cursor and mouse keys.
  • Tap-hold auto-repeat is disabled to enable faster tap-hold switching on thumbs but thumb tap keys are mirrored onto some layers for use with auto-repeat.

Layers

The layers are maintained in tables, with the thumb keys on the bottom row. 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 (excepting '"' (DQUO) and '|' (PIPE)). 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. RST and mods 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 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.

Mouse (MOUR)

Secondary RH layer is mouse emulation. Mouse movement mirrors cursor navigation on home and wheel mirrors line / page movement below. Buttons are on the thumbs. Mouse movement, click, and drag with modifiers can be performed from the home position. Unused keys are available for other related functions.

Media (MEDR)

Tertiary RH layer is media control, with volume up / down and next / prev mirroring the navigation keys. Pause, stop and mute are on thumbs. Unused keys are available for other related functions.

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 for convenience.

Shifted Numerals and Symbols (NSSL)

Secondary LH layer has shifted symbols in the same locations to reduce chording when using mods with shifted symbols. Automatically generated from unshifted table.

Function and System (FUNL)

Tertiary LH 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.

ergodox

For the ergodox layout, the main 5x3 alphas are used as usual. The primary and secondary thumb keys are the inner and outer 2u thumb keys and the tertiary thumb key is the innermost key of the partial bottom row. The remaining keys are unused.
