Manage annotations

The Toolbox add-on lets you manage annotations in PDF documents. PDF annotations are elements that allow you to add comments, suggestions, and markup like shapes and highlights to PDFs. Annotations are not part of the page content as they are applied on the top of a page. In contrast to ordinary page content, many annotation types behave interactively in PDF viewers.
