That's a solution, but it has its problems. For one, you can only see = the highlighted parts that are in the visible part of the buffer. With = arrows, you can see that the arrow goes "off the window", so you get a = clue that you should follow the arrow to see what it points to. >=20 >> But can the image in a margin overflow the margin to overlay the main = text? I assume not. >=20 > No, it cannot. It will be displayed entirely in the margin. Ok. Oh well. I guess a web-browser solution will have to do for now. Marc
