[pdftex] \popref (or whatever)

Example publishing by Ross is mind-striking


So are some examples of fancytooltips package.

hyperref brought the true on-screen reading of math texts and it is
without any efforts exceeding putting one line in preamble (unless one
wants something more sophisticated than simply clicking on the link
generated by (\ref{A}) then going to equation with \label{A} and then
hitting the ``previous view'' button on the pdf viewer.

However sometimes one needs to put something like: ``Compare this
equation with equation (\ref{A})'' and the reader should be able to
see simultaneously two equations on two different pages. No problem
because one can repeat then equation on the proper page. However  this
would lead to increased size of the article and this would be a
problem for the printed version. So, it would be very nice to have a
command \popref{A} (a whatever it is called) so that this command
would (in AR) not lead to equation labeled by {A} but to generate a
pop-up displaying this equation exactly as in example of Ross.

Surely, this functionality will be only for javascript-supporting
viewers (i.e. only AR at this moment) and one needs to ensure that for
other viewers \popref{} would work exactly as \ref{}.

Possibly it could lead to the reduced performance of both LaTeX and
pdf-viewer (hope not)
