Sort comments
You can sort comments in the Comments list by author, page, type, date, color, checked state, or status by person. In a thread of replies, only the first message is sorted, and the reply messages are sorted in the same category as the first message in the thread.

the Comments list.
Show or hide comments
You can hide or show comments based on type, reviewer (author), status, or checked state. Hiding comments is also called filtering. Filtering affects the appearance of comments in both the document window and the Comments list. When you print or summarize comments, you can specify whether hidden comments are printed or summarized. When you hide a note comment that has been replied to, all other replies in the thread are hidden as well.
From the Show menu 
in
the Comments list, do one of the following:-
To show all comments, choose Show All Comments.
-
To hide all comments, choose Hide All Comments.
-
To filter comments, choose the categories that you want to appear. For example, if you want only note comments that you haven’t checked to appear, choose Show By Type > Notes so that only the note comments appear, and then choose Show By Checked State > Unchecked so that only unchecked note comments appear.
-
To reverse a filter, choose the All command for hidden categories. For example, if you filtered comments so that only those by a certain reviewer appear, choose Show > Show By Reviewer > All Reviewers.
