AR and Preview (TS) give you images this way, which need to be
pasted somewhere for comparison.

With Skim, just Cmd-click the link then hit its yellow
traffic-light. This minimizes it into the "Snapshot" side-bar.
Do this for each equation needing to be compared.
Then bring each one back up with a click, and adjust its window
size/shape/position (and magnification, if desired).
This allows an easier way to compare the equations.

The need to adjust window sizes is a step that it would be
nice to be able to eliminate, if possible.


Also, the term "Snapshot" is now being used in two different ways.
For Skim, a better term might be "Spyglass", or something else;
especially since the view is scrollable, so not really a snapshot
at all.

Yes; but with Skim you can have many different windows,
opened and sized appropriately.

It should not be necessary to add extra images to the PDF, if that
is what you mean, since the information is already in the PDF...

  ... which is one of the downsides of my solution, which
is not shared by Skim's "Snapshots".

The 2nd downside of my solution is that you cannot choose between
the actions. My Javascript button screens the underlying hyperlink.
It is reliant on the browser to pass a click through when JS is
not activated.  AR and eVince (for Linux) do this correctly,
but Preview and Skim do not.


Thus it is really a matter of requesting the browser vendors
to implement all the methods that we researchers find useful;
preferably with a consistent interface for using them.

Having Skim doing some things differently to Preview and AR
is useful for showing Apple and Adobe what we'd like them
to be doing too.

Skim giving you the choice of "Click" and "Cmd-click" is a good
solution, IMHO.
