William,
Thank you so much for replying!  I'm not sure that you got what I'm trying to
get.  If you were to click on the "expand all" link on the
<http://asknature.org/aof/browse># web site, you'll see many further links.  I
just want to get the first page of each of those links.  I'm not sure that the
"direction: up & down" setting is what I'm trying for, really just want to go
down one level from this page.

I apologize for being a nuisance.
Baruch
