 :::info
 Functionally, the layer-tap is a [hold-tap](hold-tap.md) of the ["tap-preferred" flavor](hold-tap.md/#flavors) and a [`tapping-term-ms`](hold-tap.md/#tapping-term-ms) of 200 that takes in a [`momentary layer`](#momentary-layer) and a [keypress](key-press.md) as its "hold" and "tap" parameters, respectively.
