Reply To: Create a list of anything that uses a certain paragraph/character style

Regarding your first question, exactly. The body of the chapter/section has a different style applied to it. The RUNNING HEADER style is only for the chapter/section titles. The usual format is, for example, 1.01^tIntroduction
If I understood you correctly, yes, the script should get all chapter/section numbers where a case is present, and put them in the format I presented above.

Regarding your last idea, some cases can be encountered just once in the whole book. Other ones reoccur in the exact same form in multiple chapters, or they even occur in different forms. This shouldn’t matter much, as long as all are identified and attributed the right chapter/section they are in.
