Adding and modifying comments in PDF documents
You can add comments to PDF documents, modify your comments, and move them within the PDF document.
Let's suppose you view a PDF file in the document display and you want to comment on a phrase in the document in the form of a note.
This is how it works
Select the desired comment type (Note) from the Comment toolbar.
Enter the required text in the Note field and create the note.
Select the desired location in the document and position the note.
Save the comment.
You can change, delete or move the note any time you want.
This is how it works
Select the note icon and switch to the editing mode using the pencil to change the text.
Select the note icon on the document and position it at the appropriate place.
Select the note icon on the document to view the comment as well as the delete icon.
It is possible that several users comment on or edit a PDF document at the same time. When it is edited simultaneously, the changes made by the person who saved the notes first, for example, are adopted.
