We often have to print docs on different types of paper and I was wondering if a script existed (or could be made) which lets us enter the filename (so we can save it somewhere) and which opens the file Info panel so we can enter the paper type (in the description area below the author Title) or just asks for the type of paper and puts the answer into the description area of the file info. That way, we can always find the right paper type again. I found some discussion about how to automate it, but that's not what I need.
As I posted this questions on the Indesignsecrets blog too, it had been aswered by Jongware. His answer:
paper = prompt ("Enter paper description", "Just pick anything");
app.activeDocument.metadataPreferences.description = paper;
