As well as being able to create connections using the Connection Tool, you can use the Connections Manager to achieve the same results.  If you want to make multiple connections to the same connector or the design surface contains a lot of features, the Connections Manager makes the task much easier.  It also helps to visualise the order in which a socket's connections are triggered, something that is fundamental in determining your project's overall behaviour.

 

From the design surface, select a single connector.  The Connections Manager will then display a list of those connectors currently connected to the selected connector and a list of those connectors that may be connected to the selected connector.

 

The Connection Manager panel is shown by selecting View → Connection Manager from the menu bar or by clicking the Connection Manager button in the Standard toolbar.
