Check this post out over at Indesignsecrets. There is a script that will do just that. It is an older script; however, if you read the article in full and the comments, you will see confirmation of it working in CS6.
Is there a way to print out a list of all of styles and their difinitions?
Thanks in advance!
Search Google for terms like "InDesign style definitions," without quotes.
Thanks! That little script worked great.
