Device.setTouchable()

Overview

Sets whether Velocity responds to device screen touch events. When set to false, the app and its context and main menus will not respond.

Setting this to false disables touch-based gestures in Velocity. Gestures such as swiping up or down on a web page, for instance scrolling or dragging and zooming via touch are not responded to. However, system navigation buttons and gestures are still enabled.
