Re: PDF "dirty" trick

That's _exactly_ what I wanted (even too much :-)). It also explains why I
didn't manage to do it with "normal" pdfTeX commands ---it required
JavaScript.

Now for a harder one: pop-up window reacting when the mouse passes over a
certain point (no need to click)? I've seen in the PDF tech ref it is
possible, and know the PDF implementation. What about ConTeXt?
