Hello all,

I'd like to be able to zoom an image during a presentation.  My thinking
is that it might be possible by turning layers on and off interactively.
I see in this message:

http://archive.contextgarden.net/message/20110426.183109.fc46c5a5.en.html

that Hans said (enigmatically :-)) "And then there are viewerlayers
(acrobat) that you can turn on and off with
\goto{On}[VideLayer{mylayer}] but that's a different topic."

Any hints on how I could do this?

I'm using the latest standalone, installed yesterday.

Thanks,
Roger
