When selected, net components display blue handles. Those handles are the connectors of each component. You can drag and drop arcs from and to them. When you move the mouse cursor over a connector, the mouse cursor takes the shape of a hand, to indicate the possibility of linking components.

To drag an arc means pressing the mouse button on the blue handle and dragging it outside the component. To drop an arc means releasing the arc inside another component. The following picture represents a drag and drop:
