You can highlight the complete flow of ICOM arrows in and out of UOB nodes on an IDEF0 diagram using the Mouse-Over Highlighting feature. System Architect highlights the line or symbol node that you move your mouse over, presenting it in a different color than lines on the rest of the diagram.
Mouse-over highlighting is particularly useful when examining a multiplexed flow on a context diagram, which can be very difficult to digest on a cluttered diagram. Another advantage is that it eliminates the need to highlight a line by clicking it. If you are forced to click on a line to highlight it, the chances that you may accidentally reposition it are greater.
