Defined Term Tags
Use defined term tags only when a term is used and defined for the first time. When the term is used again later in the document, use title case (initial capitals) to denote it is a defined term. In the generated document, the text inside the defined term tags displays inside quotation remarks and is formatted with italics, for example: “Current Index.”
When you open an editing box, defined terms appear with green tags; see the graphic below.
The screen shot also shows two ways of effectively and easily defining a term—one with the term at the beginning of the sentence, and the other with the term at the end.
