I am looking for a script (CS4&5.5) to create styles groups (character and paragraph) set.
I don(t know how to script so please, if this script does not exist, explain step by step how to write it.
I'm not sure exactly what you want.
This creates a new paragraph style group:
var group = app.documents.paragraphStyleGroups.add(); group.name = "Rumplestilskin";
That is exactly what I was looking for!
