karabiner

Key remapping on macOS with Karabiner involves creating mappings in the configuration file or CLI. You define source keys (like Caps Lock) and target keys (like Escape), then apply them to your profile. Karabiner-Elements processes these rules and activates them immediately.

Yes, Karabiner supports complex modifications using variables and device conditions. You can layer rules based on application context, keyboard type, or system state, enabling workflow-specific key behavior without manual profile switching.

Profile management in Karabiner lets you create and switch between configuration sets suited to different workflows. Use the CLI (karabiner_cli) or the GUI to activate profiles, and apply conditional rules to auto-select profiles based on connected devices or applications.

Check your mappings using EventViewer to verify key events register correctly. Lint your configuration for syntax errors, verify the profile is active, and confirm no conflicting rules override your remaps. The CLI tools help diagnose and validate rule application.

Yes, karabiner_cli enables CLI-driven workflows to inspect, edit, lint, and apply configuration changes programmatically. This allows scripting and automation of profile switching, rule deployment, and configuration validation without manual GUI interaction.

Karabiner supports both built-in and external keyboards. You can create device-specific rules using conditions to apply different mappings based on which keyboard is connected, enabling tailored remaps for each input device.
