You insert section breaks in the main body of the document, not anywhere within the header and footer space. So, you would close the header and footer workspace before doing these steps. Then:
Place the cursor where you want a new section to start.
On the Ribbon, click the Page Layout
tab, and click Breaks
Under Section Breaks
, click Next Page
Word creates a section break before the position of the cursor.
Note The actual section breaks in the document don't show automatically. You can expose them in Print Layout view, with the header and footer workspace turned off, by clicking the Show/Hide button on the Home tab. You can also see them in Draft view.
(You might want to see a section break in case you change your mind and want to delete it. You'll go through this in the practice session at the end of the lesson.)
Tip You can also set up section breaks when you want content to start on odd- or even-numbered pages. See the Quick Reference Card for more information.
