About annotating and marking up documents

The following annotations are available in the Comment tab.

Note: This is like a sticky note, and can be "glued" on top of the document page.

Callout: Callouts are special text boxes pointing to the place that a comment is made on.

Text Box: Enter text phrases directly on pages with selectable font, style, color, and transparency.

Draw Tools: Enter graphic objects, or even a stamp, directly on pages with selectable shape, color, and other property settings.

Various markup tools: Emphasize text parts on pages with highlight, cross-out, or underline. Also indicate suggested additions, deletions or changes to a document.

Attachments: Attach files, sounds, movies to the document.

Comment tools like Note, Text Box, Draw, Markup, and attachments share many common properties. For details, see Annotation and Markup Object Properties.

When you have reviewed a comment, select "Set Status" from its shortcut menu to change its "Review" state and/or Migration state. See Comments panel for details.

Annotations are stored in the PDF at a different level to the real PDF content. They allow shared document commenting. See also Print with Comments.

To add new text you can also use the Typewriter tool. See Text Box to see the differences between these tools. Edit page contents and make minor editing changes to existing PDF text or objects, including typewriter text after the PDF has been saved. Annotations can be removed or turned into document objects with the command Flatten or removed by Removing Document Elements.
