Mod-Tap Behavior	Mod-Tap

Summary

The Mod-Tap behavior sends a different keypress, depending on whether it's held or tapped.

• If you hold the key for longer than 200ms, the first keycode ("mod") is sent.
• If you tap the key (release before 200ms), the second keycode ("tap") is sent.

If you press another key within the 200ms, the 'mod' behavior is also activated.

Mod-Tap

The Mod-Tap behavior either acts as a held modifier, or as a tapped keycode.

Behavior Binding

• Reference: &mt
• Parameter #1: The keycode to be sent when activating as a modifier, e.g. LSHIFT
• Parameter #2: The keycode to sent when used as a tap, e.g. A, B.

Example:

&mt LSHIFT A

Configuration

You can configure a different tapping term in your keymap:

&mt {
    tapping-term-ms = <400>;
};

/ {
    keymap {
        ...
    };
};
