Core rule: styles, not manual formatting
- Use Heading 1/2/3 styles for every heading;
- Use the Normal style for body text instead of resizing per paragraph;
- Modify a style once to update the whole document.
Contents and page numbers
- References → Table of Contents → automatic; right-click and Update Field later;
- Insert → Header & Footer → Page Number, set a different first page;
- Leave the cover unnumbered with Layout → Breaks → Next Page, then unlink from previous.
Figure numbering
Use captions for figures and tables; cross-references renumber automatically when you insert or delete items.
