Menu: Extra Tools --> Toggle connections

This tool applies connections to wires at wire junctions. 

Note that if any connections exist on the schematic then they are removed when this tool is first used.  When the tool is used again the connections are applied.

Connections are applied to the junctions of horizontal and vertical wires.   They are only applied if  more than two wires meet at a point.   These rules apply the connections as you would expect to see them.

To save processing when moving parts around the schematic not all wires are tested for connections and it may be necessary to reapply the connections after wire dragging.

Note : Automatic connections can be turned off from menu Edit-->Options-->System-->Auto connections
