To manually create a single mapping, select a connection point and drag it to the connection point of a port attribute.
You can also change existing mapping lines. If you want to change the current mapping, select the mapping line at the connection point and drag the line to an unmapped port attribute.
To delete a single mapping, select the mapping line and press the Delete key, or right-click and select Delete from the pop-up menu. To delete all mappings of a link, click Delete, or select Mapping | Remove All.
