I just meant earlier IIRC the PDF viewers didn't always seem to work consistently
but I'm not sure where they are now- I just use evince.

That is a large part of what Tex does and then complains about badness
or something trying to add whitespace as best it can to accomodate
page break for floats.

I guess I saw expand/collapse first on some html and thought the idea was nice.
It is easier to collapse inline rather than going to a table of
contents, then to some fragment surrounded by the other junk,
and then back etc. Flipping pages is just that, but often you
want to flip through logical groups- maybe like the paragraphs
someone else mentioned in legal citations. My play code actually
does that, it sets up groups numbered in order ( I have thinks like "title"
and then the dvi has things like "title1" "title2" etc but they could
just as easily be paragraphs). If you can change the visibility that
way at the right granularity you can even end up with a small amount
of stuff to scroll through without contrived paged breaks for
a meaningless geometry ( that the viewer software probably struggles to accomodate too ).
And when you are done, just looking at what you want, it may even be
easier to copy/paste or otherwise cite/share.

As I understand it, these are just link to fragments not blocks that can
be manipulated as a whole but I
could be wrong especially about PDF.

Thanks, I thought there might be and it will take me a while to look
at those that have been suggested in these replies but at this
point I was just curious about what people even find desirable-
I was even suprised by the page turning graphic lol.
Personally, I don't see a need for proporational space fonts
except for things like math but if you have it there it
may as well be used everywhere.

I was going to mention papyrus :)

Thanks, these are the kinds of things I'm curious about. The page
though, with a physical size specificed in the latex document,
sounds irrelevant now. The viewer ends up having to accomdate the
viewing window anyway and that is all that matters without having
to consider a legacy page notion AFAICT.
