zmk-config

This is my personal ZMK firmware configuration. It is ported from my QMK configuration, which in turn is heavily inspired by Manna Harbour's Miryoku layout.

Key features

• clean keymap config + unicode support using zmk-nodefree-config
• home-row mods on base layer, sticky mods on Nav and Num layers
• most symbols can be accessed from the base layer via combos
• sticky shift on right thumb, double-tap activates caps-word
• backspace morphs into delete when shifted
• full numpad-layer with arithmetic operators (= via combo) and Esc, Enter, Tab on left hand (can be numlocked via W + P combo, ideal for data entry and right-handed mouse)
• "Greek" layer for mathematical typesetting

A few thoughts on the combo setup

The combo layout is guided by two goals: (1) put all combos in easy-to-access locations, and (2) make them easy to remember. Specifically:

• the top vertical-combo row is almost equivalent to the symbols on standard number rows, making them easy to remember
• the bottom vertical-combo row is set up symmetrically to facilitate memorization (subscript _ aligns with superscript ^; minus - aligns with +; division / aligns with multiplication *; logical-or | aligns with logical-and &; backslash \ aligns horizontally with forward slash /)
• parenthesis, braces and brackets in symmetric positions
• ! and ? are on home-row position for prime access
• a numlock shortcut (on W + P) for one-handed data entry
• shortcuts for cut (on X + D), copy, and paste on the left-hand side for right-handed mouse usage
