If you are saying you would like to delete all the comments, then you can do that from the
Review tab: in the Comments group, click the arrow under
Delete and choose Delete All Comments in Document.
If you opt to display comments in balloons, then the Comments
sidebar will not be displayed:
- In the Tracking group of the Review tab, for
Show Markup, select the markup items you want to see (if the document contains only comments and no tracked changes, it won't matter what you select provided you leave Comments selected).
- For Balloons, select Show Revisions in Balloons or
Show Only Comments and Formatting in Balloons.
- Click the dialog launcher (small arrow) in the bottom right corner of the Tracking group.
- In the Track Changes Options dialog, select Revisions or
Comments and formatting for "Balloons in All Markup view show."
- If you click Advanced Options..., you will get a dialog where you can specify the width of the markup area used for the balloons.
- Click OK to close both dialogs.
Now, when you select All Markup, you will see the comments in balloons in the right margin. When you select
Simple Markup, you'll see a balloon icon indicating a comment; you can click on that to see the comment. When you select
No Markup, you won't see the comments at all.
