Ukelele

Ukelele provides a graphical interface for creating, modifying, and testing keyboard layouts that map Unicode characters to key presses. It lets users define custom key mappings, assign multiple characters to a single key, and specify dead‑key sequences, enabling the construction of input methods for any script or symbol set. The editor writes the resulting layout files in the format required by the operating system, allowing immediate activation without manual editing of configuration files.

The tool is aimed at developers, linguists, and power users who need to support languages or specialized symbol sets that are not covered by default system keyboards. By offering a visual layout editor, it reduces the need to edit raw XML or binary files directly, making the process more accessible to those with limited programming experience.

Ukelele is released as a stable utility, and the core features of Unicode‑aware layout design and export. It runs on the supported platform and integrates with the system’s keyboard infrastructure, allowing the created layouts to be used by any application that relies on the standard input system.
