Referencing and Indexes
Long documents need automated referencing so that page numbers, captions, and citations update as content changes. Candidates must understand bookmarks and cross-references (to headings, figures, tables, footnotes, or bookmarks), captions for figures/tables, footnotes and endnotes, and tables of contents, figures, and authorities. A TOC is generated from Heading styles (or specified styles) and can be updated to refresh page numbers or the entire entry list. A table of figures is built from caption labels.
For academic or professional writing, know citations and bibliography (source managers that insert in-text citations and build a reference list in a chosen style) and indexes built from marked index entries with cross-references ("see" and "see also"). Understand that fields (TOC, cross-reference, page number) are dynamic and may need updating (F9), and that printing can update fields automatically.
Traps: assuming a cross-reference to a heading shows the heading text when it may show only the number, or vice versa - the inserted cross-reference type matters. Another trap: a TOC that is empty or incomplete because headings used direct formatting, or because the TOC was set to a heading level that excludes those headings. Also, updating a TOC's page numbers only will not add newly added headings - a full update is required.
Worked example: To cross-reference a figure, insert a caption (e.g., "Figure 1"), then Insert > Cross-reference > Reference type: Figure > Insert reference to: Entire caption. Rule of thumb: reference fields, not typed numbers, so edits don't break references.
