SixArm Karabiner-Elements

Karabiner-Elements is a macOS application that enables keyboard changes such as remappings of the caps lock key, control key, escape key, and much more.

We especially like these remappings that we use with vi, emacs, tmux, and similar kinds of command-line applications:

• Change from caps_lock to control (if held) or escape (if released)

• Change from right_command to control-b tmux prefix

Install

To install, copy the file you want to your Karabiner-Elements assets directory, such as:

~/.config/karabiner/assets/complex_modifications/

Enable:

• Launch Karabiner-Elements as usual.

• Tap the icon in your macOS menu bar.

• Choose the menu item "Preferences...".

• Choose the tab "Complex modifications".

• Click the button "Add Rule".

• Scroll to find the rule, then click the button "Enable".

Customization

You can customize these files as you wish.

You can also create your own files, the same kind of way.
