By default, the microphone key on some Keychron models doesn’t trigger macOS dictation. With Karabiner-Elements, you can remap that key to launch dictation or any other system function.

This setup allows you to start voice dictation with a single key press, improving workflow efficiency.

To make the microphone key on a Keychron keyboard activate dictation in macOS, follow these steps:

1. Open Karabiner-Elements
2. Go to Complex Modifications → Add your own rule
3. Paste this script.
