When opened the point list will be set to display nothing with No robot selected. A robot can be selected using the Part Top Selection dropdown at the top of the display window on the right side of the Device tab. The active selection will still be shown in the dropdown, with a blue highlight.
The point in a point list that is active is marked with an arrow. When working with multiple robots, an arrow marker will also appear for any point that is being simultaneously activated by another robot, when that robot is selected. The markers are synchronized based on where in the simulation they are, in tandem with said simulation’s own marker.
