Some merge fields are actually made up of other fields. For example, the Address Block field is a combination of first name, last name, street address, city, and postal code.
You can create a merge field by combining other fields, or you can group fields and then use spaces, line breaks, and punctuation marks as you would normally in a sentence. For example, you might want to create a courtesy title before the surname or full name and set up fields in your document like this:
«Title» «Last Name»
«City», «State» «Postal Code»
You can also control how recipient information looks in the merged documents by formatting the fields. For example, you might want names to be bold or colored red. In the main document, select the field, including the surrounding chevrons (« »). On the Home tab, click any command in the Font group or the Paragraph group, or click the Dialog Box Launcher for either of these groups and choose the formatting options that you want.
