Karabiner
Karabiner is a system-level keyboard remapper and input modifier for macOS. It functions as a kernel-level interceptor that modifies raw hardware events before they reach the operating system, utilizing a virtual hardware device to inject synthesized keyboard and mouse actions.
The project distinguishes itself as a context-aware input manager, applying modification rules dynamically based on the active application, connected hardware, or current input source. It serves as a keyboard macro engine capable of automating multi-key shortcuts and conditional behaviors.
Its broader capabilities include translating individual key presses and mouse buttons into alternative outputs, shell commands, or system functions. The framework supports input sequence automation based on timing and hold durations, device-specific filtering, and the import of predefined community-created rule sets.
Configuration is managed through a structured data schema, allowing users to save and switch between different input profiles.
