Reply to comments
Note:

They can also be used by review initiators to let reviewers know how their suggestions are being implemented. When one or more reviewers reply to a comment, the set of replies is called a thread. In the Comments list, all replies are displayed. Replies are indented below the original comment.

In Windows, you can use a status or a check mark to indicate which comments you want to export to a Word document. By setting the review status, you can show or hide a group of comments and let review participants know how you are going to handle the comment.

Check marks are for your personal use and do not appear when others view the PDF unless you change the status of comments.
