34 keys is all you need: an ergonomic keyboard journey
summary
Claim: a 34-key split keyboard provides full desktop functionality while cutting strain and travel. Hardware choices are columnar stagger, split halves, thumb cluster, splay and concave wells; software uses ZMK firmware features (layers, mod‑taps, auto‑shift, combos, caps word) to map numbers, nav, symbols and media across layers. Implementation: a Bluetooth 34‑key build running the Miryoku layout replaces full‑size keys (Escape/Delete via combos, numpad on left, arrows on right), proves usable daily after ~2–3 weeks and reduces ergonomic issues.
