Wiring One Node to Another
To begin wiring, click and hold down the left mouse button on a node. The mouse pointer now becomes a spool of wire indicating that you have started pulling a wire. While holding the left mouse button down drag the mouse pointer to the node that you want to wire to. As you drag the mouse pointer, a wire will appear connecting the node of origin to the spool. When you are over the desired node (the crosshair above and to the left of the spool of wire is the actual selection point) release the left mouse button. The mouse pointer will now change back to a phone plug indicating that you may continue wiring. The wire will remain, connecting the two nodes.
