An Edge Pan trigger fires when the user moves their finger across the screen, starting from one of the device’s edges. Edge Pan triggers can fire once when the pan begins, continuously while the user pans, or once when the pan gesture ends.
The difference between an Edge Pan trigger and a Pan trigger is whether the pan begins at the edge of the screen or elsewhere on the screen.
