A paragraph is a block of text that ends with a paragraph marker (¶), which you create by pressing the Enter key on the keyboard. The marker symbol does not print, and it does not show up onscreen unless you have configured Word to display nonprinting characters.
Pressing Enter starts a new paragraph (and ends the previous one), but not all line breaks are paragraph breaks. You can create a line break that does not start a new paragraph by pressing Shift+Enter. A line break is represented by the nonprinting symbol. (Again, the symbol doesn’t appear onscreen unless Word is displaying nonprinting characters.) Figure 5.1 shows examples of paragraph breaks and line breaks.
