A page break is generated automatically. When you fill a page with text or pictures, Word inserts a page break and starts a new page automatically. To induce a page break, put a manual page break at a certain point. For example, you could place the cursor at the beginning of a chapter and select Page Break from the Home tab. Or, if you want a page break to occur every time you type the word 'hello', place the cursor at the beginning of a document and click Edit > Preferences > Auto Corrections. In the Correction list, select Hello from the drop-down menu and press OK.
