Use the Comments List

The Comments List shows all the comments in a PDF document. From this window, you can read and manage comments, delete or reply to them, or mark them with checkmarks to show that you’ve read them. When you select a comment in the list, the PDF document scrolls to the comment in the document pane. You can view comments by author, date, or page number. Each comment displays its associated text next to the comment icon. If you edit this text, text in the document window updates accordingly.
