Changing arrow direction on a link
You can change the direction of the arrows on links. To show a two-way relationship between two symbols, for example, you could add arrows to both ends of the link. Other times, you may want no arrows for a link. Changing the arrow direction on a link has no effect on the relationship between the symbols. To change the relationship between symbols, you must reverse the link. See Reversing a link.
