Action Points allow the assignment of a VirtualDJ script action which executes once the track reaches that point. A Macro action field is provided on the right side to type the action and a radio button is offered to open the Macro Editor to help choose the desired action.
In the above example the action goto +32 is assigned to the Action Point. When the track reaches this POI it will automatically skip 32 beats seamlessly.
