Keys

Remap keys, paste snippets, show keystrokes.

Remap keys — turn a key, a combination, or a double-tap into another key or a special action
Switch language with one key — e.g. Caps Lock flips between English and Russian
Snippets — press a key, type a few letters, paste a saved piece of text
Show keystrokes — great for demos and videos

Configuration

All settings live in ~/.config/keys/keys.conf. Open it in any editor — changes are picked up as soon as you save.

[remap]
caps_lock: toggle_input
option+shift+a: control+b
control, control: snippets

[snippet]
Hello world
em: my.email@example.com

Remaps use input: output lines (join combinations with +, double-taps with , ). Snippets are one per line; prefix with a keyword like em: for fuzzy search.

Special outputs include snippets, toggle_input, open(Safari), bash(say hello), paste(Hello!), and ignore.

On first launch

macOS will ask for Accessibility and Input Monitoring access in System Settings — both are required to see your keystrokes.

See the full config reference on GitHub.
