How to edit right-side scroll display tags or box

[westrism]

I'm not sure what this space is called and have searched and searched for information on how to edit the display tags that appear as you scroll through a long document. I've inherited a document from an older version of Word, and am now in Word 2010. I can not determine if the tags correspond to styles or headings or bookmarks. Any help is appreciated. Thanks!

Hi westrism,

If you can take a screenshot showing what you're trying to describe and attach it to a post, we can probably give some specific advice. As even you aren't sure whether you're referring to styles or headings or bookmarks, it's a bit hard for us to know too.
