Deleting Wires
If you want to delete wires you can do so as long as you are in the wire mode. First highlight the wire that you want to delete. You do this by moving the mouse pointer over either the wire you want to delete or one of the nodes on either end of the wire. If you are over the wire the wire will highlight by turning red. If you are over a node a red selection box will appear around the node. Next use the delete key on the keyboard to delete the selected wire.
You can delete multiple wires by selecting multiple wires or nodes in the following manners:
You can drag a selection rectangle around the desired wires. You need only cross all of the desired wires, it is not necessary to include the entire wire in the selection rectangle. The selected wires will be highlighted in red.
You can select the wires by using Shift+Click or by dragging a selection rectangle around the desired wires. The selected wires will highlight in red.
You can select multiple nodes from either side of each wire desired by using Shift+Click or by dragging a selection rectangle around them. A red selection rectangle will highlight each node selected.
