Well, the real problem is (at least for a mathematician) the line

Comparing equations (8.1), (7.9),(5.3) and (1.4),...

With AR  or TS  etc you click on the link (8.1), select page area
using corresponding tool:

rectangle tool in TS and Skim  or snapshot tool  in AR (looks like
photo camera; remember in AR you can customize toolbar), copy it (in
TS you press Cmd-C, in AR it is done automatically), paste it as
graphics in TextEdit (or any graphics editor) window, go to previous
view (thus returning to the page you are reading) and repeat the
procedure for each of equations. So you end-up with the TextEdit
window containing all these equations and can actually compare them.
Beside equations it could be theorems etc

This is not extremely convenient but (1) it is far more convenient
than for a printed paper where your snapshot tool is a pencil and a
paper (2) Adobe' people think that they already provided us with all
tools needed.

I definitely believe that just going back-and-forth without copy-paste
makes comparison rather superficial unless there are very few very
short equations. This would be true and for another window displaying
at any moment just one of the equations you want to compare.

Surely if you are the author you can always write: Comparing equations
(\ref{A}), (\ref{B}),...
$$............... \tag{\ref{A}}$$
$$............... \tag{\ref{b}}$$

but using this trick frequently would increase the number of pages
with  grave consequences for printed article; even pdf article will be
overburdened.

Luckily Ross demonstrated a solution in a different mailing list
(works only in AR since only it understands Javascript). Hopefully he
will make a package.

Right now beside of asking him 'pretty-pretty-please" one can achieve
similar effect  but not as nice looking (and actually requiring some
cumbersome work from the author) using fancytooltips package by Robert
Marik. What is worse: with Ross solution viewers different from AR
just follow the link, while with solution based on fancytooltips
package it does not work

While this definitely is not endemic to MacOSX, I think that asking
Ross for a really correct tool should be made in any occasion. I would
prefer, however, if (say) control-clicking on link would actually
follow it instead of pop-up (so the reader can chose between pop-uping
and going).
