How to find out what paragraph style is based on another style
I do book typesetting and sometimes have to hand over the InDesign file to the client. Before doing so, I like to clean up the paragraph styles and make sure all unused styles are deleted.
In a current project, I've got a style that isn't used on any text (I've done a "Find Format" on the document and it doesn't turn up any results). However, it doesn't get selected when I "Select all unused" in the paragraph styles window. When I try to delete it, it asks what I want to replace it with. So I'm assuming that a different style is based on that (otherwise) unused style. I've got quite a few styles in the project, however, and was hoping to avoid the tedium of manually checking each one to see what other style is based on it.
It seems like there should be a simple way to find out what styles are based on another style, but if it exists, I haven't been able to find it. Am I overlooking something simple, or is there really no quick way to find this info?
