This is a second generation feature that lets you rest your fingers on the AirTriggers buttons, then press down to trigger continuous AirTriggers functions. After you tap the buttons to trigger for the first time, you don't have to lift your fingers, just press down again to trigger for the second time, and so on. It's good for shooting games.
To enable this feature, launch Armoury Crate > Console > AirTriggers > toggle to turn on Finger resting.
