HyperJIS: One Keyboard Layout, Any Apple Machine
Summary
HyperJIS is a Karabiner-Elements configuration that repurposes extra keys on Apple Japanese keyboards to create a US-compatible layout with a Hyper key, Vim navigation, window tiling, and accent support for Italian, French, Spanish, and German. The post explains why the JIS layout provides more keys, details the modifier cascade, describes Vim-style navigation, and outlines a modular accent system with language extensions; it also covers installation and licensing (GPL-3.0).
