Highlighting Links
By default, when you select an output field, the Flow Designer highlights the chain of links. To enable or disable highlighting, right-click in the mapping area and select the option to highlight links to fields.
Note
You can also enable or disable highlighting by default in the Flow Designer's environment settings: In the main menu, click Tools > Settings and, on the View/Edit tab, select or clear the option to highlight links when you select an output field.
