But since you want the arrow to appear only when the mouse pointer hovers above one of the places that are involved in a relationship, how about highlighting those places in some way, when mouse is over one of them, without actually drawing an arrow? > But can the image in a margin overflow the margin to overlay the main text? I assume not. No, it cannot. It will be displayed entirely in the margin.
