Selecting a line

A line connecting two steps consists of a sequence of segments that are alternately horizontal and vertical. A straight line consists of one segment only. For example, a line connecting a choice step with its lower follower consists of three segments: one horizontal to the left, one vertical downwards and second horizontal to the left.

You can select a line in the design mode by clicking on it. Once a line is selected its ending points as well as the middle points of each of its segments become marked by small circles - the ends by green ones, the middles by white ones.
