You can specify how to display cross-references to numbered paragraphs in the Cross-reference dialog box by clicking Numbered item in the Reference type box and then clicking Paragraph number, Paragraph number (full context), or Paragraph number (no context) options in the Insert Reference to box.
For example, suppose that you're working on a legal document that contains outline numbered list (outline numbered list: A list created to apply a hierarchical structure to any list or document. A document can have up to nine levels, and Microsoft Word does not apply built-in heading styles to the items in the list.) items or LISTNUM fields (field: A set of codes that instructs Microsoft Word to insert text, graphics, page numbers, and other material into a document automatically. For example, the DATE field inserts the current date.), as shown in the following illustration.
If you choose the Paragraph number option, and then include a cross-reference to paragraph 1.(a)(ii) in paragraph 1.(a)(i), the reference appears as "ii."
