Commenting provides revision tools for people reviewing and sharing
documents. You can mark places in your PDF by highlighting sections, drawing,
adding notes, lines of text, stamps, and more. For example, you can circle
a diagram and add the text “Make this diagram bigger”. This text will
appear when you hover the cursor over the object.
Annotating and Marking
up Documents provides a set of links to each comment type. See also
Print with comments.
All comments are added to the Comments list and are displayed in the
Comments panel with a number of convenient tools to manage them.
Enable the Comments panel from the 
Navigation Panels drop-down list.
