Hi Ross!

That is very helpful. Thank you! Where is this “run” thing documented?

Well, that depends upon how detailed information you want.

The PDF Reference v1.7  (also known as ISO 32000-1)  tells you all about how the PDF bits
need to be constructed. But that may be too detailed for you.

At the TeX/LaTeX level, I think the "LaTeX Web Companion" is probably best.
This tells you what is implemented in hyperref  and supported by pdfTeX,
though I cannot find any reference to ‘run’ there.


Here are snippets, including actual coding, from  hyperref.dtx :


\def\@pdftempwordrun{run}%


% If the URL type is `file', pass it for local opening
%    \begin{macrocode}
      \def\@pdftempa{#4}%
      \ifx\@pdftempa\@pdftempwordfile
        \@hyper at linkfile#7\\{#3}{#2}{#7}%
      \else
%    \end{macrocode}
% if it starts `run:', its to launch an application.
%    \begin{macrocode}
        \ifx\@pdftempa\@pdftempwordrun
          \ifHy at pdfa
            \Hy at Error{%
              PDF/A: Launch action is prohibited%
            }\@ehc
            \begingroup
              \leavevmode
              #2%
            \endgroup
          \else
            \@hyper at launch#7\\{#3}{#2}%
          \fi
        \else
%    \end{macrocode}



Hope this helps.
