Karabiner-Elements

Karabiner-Elements is a keyboard customization tool for Mac that allows you to adapt the keyboard layout to your preferences. In the style of classic remapping apps like SharpKeys on PC, this open-source tool offers features with greater technical depth to help you effortlessly optimize your workflow.

Full customization of keys and devices

Karabiner-Elements makes it very easy to remap any key individually or create complex rules to change the behavior of your entire Mac keyboard. One of the software's most interesting features is the ability to transform Caps Lock into an additional Control key or even a "Hyper Key" (a combination of Shift+Control+Option+Command). What's more, the program gives you the option to distinguish between different connected devices. This means you can apply a specific configuration for your MacBook's built-in keyboard and a completely different one for any mechanical keyboard or multi-button mouse you use at your desk.

Automation and complex rules

In addition to the classic key swapping, Karabiner-Elements also supports "Complex Modifications". Thanks to a library of rules created by the community or using your own configuration files, you can program actions that activate only in specific apps or that depend on how long you press the keys. For example, you can configure a key to act as "Escape" if you press it once, but as "Control" if you hold it down. The versatility is so great that you can emulate mouse behavior using just the keyboard.

What I liked most about Karabiner-Elements and what could be improved

• What I liked most: The flexibility to make complex modifications and the ability to manage different profiles for each connected device are its greatest strengths. The automatic recovery engine update makes the software quite reliable.

• What could be improved: Creating custom rules requires you to become familiar with JSON files, which may limit some users at first.
