Statuses and check marks are useful for keeping track of comments that you’ve read or that require further action. 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. Once the review status is set, you cannot remove the review status display from the comment in the Comments list, even if you change the review status to None. Check marks are for your personal use and do not appear when others view the PDF unless you change the status of comments.
