History

  1. 2020Its author starts on Workman, then learns Colemak-DH, Colemak, Dvorak and Semimak.
  2. Mar 2022Posts three siblings made with semilin’s genkey: Sertain, Nerts and Nerps. Nerps trades a few more same-finger pairs for lighter pinkies.
  3. 2023Gallium is built from Nerps.

Design goal: Avoid redirects, keep same-finger pairs low and spare the upper pinky keys.

Pros

  • Very few redirects, about half the rate of most layouts by its author’s estimate.
  • Light pinkies by design.
  • Its most common same-finger pairs are easy to work around, and it led directly to Gallium.

Cons

  • More same-finger pairs than many modern layouts, by its author’s own comparison.
  • Known awkward pairs include SW, SC, BY and PS.
  • Only published as a forum post, with no installers.
