# Bookmark Editing
Bookmarks allow us to navigate a pdf quickly, to different chapters, sections, etc. Such efficiency is impossible on a physical copy.

## Adding section numbers
Often, there are pdfs whose bookmarks do not show the chapter/section number, eg[^Szeliski]
[^Szeliski]: From Richard Szeliski, Computer Vision: Algorithms and Applications, 2nd ed. Available on https://szeliski.org/Book/

So I wrote a script (`formatter_test.py`) to add the chapter/section number automatically:
