Page properties – including margins, page numbers, number of columns, horizontal or vertical format, etc. The template contains two section breaks – just before the Table of Contents, and at the beginning of Chapter 1. For example, one section can have page numbering in Roman numerals, while another section can use Arabic numbers.
Within sections, it is possible to vary the layout of the document. Word uses section breaks to divide a document into sections. To insert a manual page break, follow these steps: (Don’t press the Enter key repeatedly until a new page begins.) In cases where you need to have text begin on a new page, such as the beginning of a new chapter, insert a manual page break at the point where you want the new page to begin. To force a page break at a specific location, you can insert a manual page break. When you fill a page with text or graphics, Word inserts an automatic page break and starts a new page.
