Since buying a new computer, which meant moving from windows 7 to
windows 10, I've been having trouble with the reverse part (pdf to lyx)
of forward and reverse search. I use SumatraPDF. I finally took the
trouble to consult the wiki. Both forward and reverse search now work
like a charm, including with a split view window in LyX. So thank you to
whoever is responsible for the instructions on the wiki.
