Moving influence
arrows

With influence arrows, unlike flow arrows, you can change the route
taken by the arrow. Simply drag any part of the arrow, and the whole
arrow will be redrawn along a new curve.

Where an influence arrow is broken into several segments, as it
traverses submodel boundaries, each segment is treated independently.
Thus, dragging one segment only affects that segment. Dragging a node at
the start or end of the influence arrow likewise only affects the first or
last segment.

You can move the dot where the influence arrow crosses a submodel
boundary. This changes only the two segments that enter or leave the
dot.
