The macro in: https://www.msofficeforums.com/128199-post4.html is sufficient to confirm whether the whole document uses the same font and/or point size. For a macro to list all fonts used in a document, see: Eileen's Lounge • View topic - Find list of font types in a document by Word macro. Once you know what fonts are in use, a simple Find for a given font's name will locate it.
