NSEvent.PressureBehavior.primaryDeepClick

A pressure gesture’s behavior begins on left mouse-down events. Two stages are supported, and a stage transition animation may occur when moving between stages—from stage 1 to stage 0, stage 1 to stage 2, stage 2 to stage 1, and stage 2 to stage 0. With this behavior type, stage 2 becomes disabled once dragging occurs. When this behavior is configured, actuations occur during the mouse-down and mouse-up events, as well as when force click is activated and released when entering or exiting stage 2. This configuration is ideal for responding to force clicks. Note that the pressure gesture operates on a separate event stream from the mouse events.
