Basic knowledge of working with the commenting tools in Acrobat
The plus sign (+) to the left of a page number indicates that the page contains comments. Click a comment in the list. If the comment is located on the portion of the document that is displayed in the Document pane, it is highlighted.
Comments are organized in levels within the Comments List.
Here are some tips for viewing comments:
Working on a long document can involve dozens or even hundreds of comments. That’s a lot of information to keep track of.
Here are a few tips for working with comments:
You can click anywhere on a comment’s listing in the Comments List to display a text field used to add a note to an existing comment. It isn’t the same as adding a reply because it originates with the person creating the original comment.
Sometimes you need to add information to a comment, such as explaining why you want to make a change in the document. Such notes appear in a tooltip when the pointer moves over the comment on the document page.
One of the simplest methods of organizing your work is to add checkmarks to selected comments. Click the comment to select it, and then click the Checkmark tool, or right-click (Control-click) the comment in the Comments List or on the document and choose Mark with Checkmark from the shortcut menu. Checkmarks aren’t shared with other people as part of a review; you use them to organize your own work. For example, add checkmarks as you finish a correction.
