To Disconnect a Wire from a Port

Choose and right-click a wire near a port.
Note: Disconnecting a port requires that you right-click the side of the wire on which the desired port is located.
Select Disconnect this wire from.
The wire becomes dynamic to the pointer.

Note: You can only disconnect a wire from a port if a wire is docked at two ports.

Note: Deleting (using the Delete this wire option) a wire from a port removes the entire wire.
