The header and footer group control the text that is displayed at the top and bottom of every page of a document. The top of every page is the Header Row. The bottom of the page is the Footer Row. Text that is inserted into the header row is displayed on every page of the specific section (most documents only have one section, but you can change the header by creating a section break). Often, the header contains the title of the document and the author, and the footer contains the date the document was created or page number. Clicking on the drop-down arrows for header and footer creates standardized options for a header and footer, but the user can customize the rows to their liking. The Page Number command provides options for how to insert page numbers throughout the document. The benefits of Microsoft Word inserting page numbers or doing it manually is that Microsoft Word automatically adds page numbers if pages are modified.
