Capewell keyboard layout

Capewell is a 2005 layout generated by an evolutionary algorithm to cut finger movement by about half compared with QWERTY while keeping Z, X, C and V in place for shortcuts.

History

  1. 2004Michael Capewell makes Capewell-Dvorak, a hand-tuned fix for what bothered him about Dvorak, such as the scattered Z, X, C and V.
  2. 2005Inspired by Peter Klausler’s Evolved program, he writes Keyboard Evolve and lets it generate the Capewell layout.
  3. LaterHe releases it up to version 0.9.3 as work in progress, then stops working on layouts.

Design goal: Cut finger movement by about half against QWERTY and favour comfortable same-hand combinations, with Z, X, C and V kept for shortcuts.

Pros

  • Z, X, C and V stay in place, so undo, cut, copy and paste do not move.
  • Generated by a published program with explicit goals.
  • Cuts finger movement by about half against QWERTY.

Cons

  • It never reached version 1.0, and development has stopped.
  • The installers came from a website that is now offline.
  • Several overlapping variants (Capewell-Dvorak, QWERF and Capewell 0.9) make it confusing to pick up.
