In LYX, how do I set up two independent viewers for the same file format?

Question

I would like to have two independent file viewers for SumatraPDF and Acrobat using the same file format (pdflatex=pdf2). What is the easiest way to achieve this?

The viewer seems to be connected to the file format so I either use one or the other right not. But I would love to be able to switch between the two!

Sumatra gives you forward and inverse search, but Acrobat prints nicely.

If you can set your own program as a PDF viewer, the easiest is to write a script that calls both viewers, and to instruct LyX to use this script as PDF viewer. If you are under Unix, the script would be something like

#!/usr/bash
sumatraPDF "$@" &
acroread "$@" &

However, you are probably using Windows: in that case you could create a batch file with something like

start "sumatraPDF" "/path/to/sumatraPDF.exe %1 %2"
start "Acrobat" "/path/to/acrobat.exe %1 %2"
