How would I do the find/replace for all headers and footers? Especially as even/odd pages and the different sections (chapters) have different information. My goal is replacing the manually typed copyright date and owner with crossreferences to bookmarks containing this information.

Also, when I copy a crossreference to the bookmark, and paste in Find/Replace it appears to convert it to text, and it's certainly text after it's replaced (in the footer). (Too bad the find and replace fields don't have a right-click Insert Crossreference capability.)
