Universal Control Remapper Link Apr 2026

Overview Purpose: define a clear specification, architecture, and implementation plan for a Universal Control Remapper Link (UCRL) — a portable, secure, and extensible protocol and reference implementation that links input devices, system-level remapping engines, and cross-device control sharing (e.g., keyboard/mouse/trackpad control, hotkeys, macros) so users can remap and route controls consistently across OSes and networked hosts.
