When inserting or editing a cross-reference, the following options are available for selecting a target:
- Link to—Select the type of targets—Anchor, Paragraph, or Index Mark—to show in the targets list.
- Target chapter—Select the book chapter that contains the target for the cross-reference. (Available when the current document is a chapter of a book that is open on the Books panel. Only chapters whose documents are open can be selected.)
- Filter style—When linking to a paragraph, select a paragraph style that must be applied to a target for it to be shown in the targets list.
- Filter text—When linking to a paragraph, enter text that a target must contain for it to be shown in the targets list. Click the magnifying glass icon to select whether the filter text must appear at the target's start or anywhere in the first 100 characters.
- Targets list—Shows all targets of the selected type and matching the filter criteria. Select an entry to link the cross-reference to it.
When you link a cross-reference to a paragraph or an index mark, it will ultimately link to an anchor at the paragraph's start/the index mark's position. Affinity uses any anchor that already exists at the position, or create a new one there.
Cross-references cannot be linked to targets within placed documents.
