Installation and Use

Karabiner Elements is a lightweight application, but it packs a wide array of functions that can change the basic functioning of your MacOS desktop or laptop.

Be aware that after installing it you also need to add it to the list of the applications that can take control over your Mac. You can do so by opening your System Preferences and adding it to the list of apps in Security & Privacy tab.
 
After this is done, the app will appear in your status bar with a small icon that describes currently loaded profile. Clicking on profile name will open a drop-down menu with the list of the currently available profiles, shortcut to the Preferences screen, app updater and the shortcut to the EventViewer service that can help you check if the various shortcut settings are actually effective inside your specific applications.

Profiles can be switched either via status bar menu or with the custom keyboard shortcuts. In the Preferences window, you can create new Profiles in the MenuBar tab, and set up the exact keymapping rules, key repeat timing, and status messages.

It is important to note that search for specific keybindings can be accelerated using the built-in search tool inside the Change Key tab.

Novices can edit customization offerings presented by the app, but seasoned users have full freedom to create and manage their own private.xmp file holding all their keyboard customization options.
