Karabiner Elements

Karabiner‑Elements is a keyboard customisation utility for macOS that lets users remap keys and create complex input behaviours. It provides a graphical interface for simple key‑mapping configuration and supports a library of community‑maintained predefined rules such as diamond‑cursor navigation, Emacs‑style shortcuts, Vi‑style bindings, and mouse‑key emulation. The software runs on both Intel‑based and Apple Silicon Macs and offers binaries for macOS versions from Mavericks through the latest releases.

Advanced users can author their own modification files to modify existing behaviours or define entirely new ones, giving fine‑grained control over how the keyboard interacts with the system. The project is maintained as a stable release, with versioned downloads for each supported macOS release and a public repository for issue tracking and contributions.

By combining an easy‑to‑use GUI for basic remapping with the ability to write custom rule files, Karabiner‑Elements serves both casual users who want quick key changes and power users who need sophisticated, scriptable keyboard modifications.
