How does the Bookmarks from Regex Pattern work?

Scan a PDF for text matching a regex pattern and add a bookmark for each match. Default pattern matches "Chapter N" headings; change it to suit your document β€” `^Section [A-Z]\.` for legal sections, `^\d+\.\s+\w+` for numbered headings, `^[A-Z][A-Z\s]+$` for ALL-CAPS lines. Each match becomes a bookmark with the matched text as its title, pointing at the page where it was first seen. Different from Auto-Bookmark from Headings (which uses font-size detection) and Add Bookmarks from CSV (which uses an explicit list). Powerful when your document follows a consistent format the heading-detector misses.
