Annotate and markup tools

Note (without highlight)	A Note icon is placed and a Note text window pops up for you to type your note text: While you are writing, a linking shape is displayed that connects the window with the icon. If you close the window and hover over the icon, the note text is displayed in a box.
Callout (special text box)	Place a somewhere in a clear place, point with the arrow to a certain object in your PDF and make your comments. When done, both the callout and the text remain visible. The Text Box tool works practically the same way, but without the arrow.
File Attachment	Find this on the Comment. Use it to select a file to appear as an attachment at a defined point in your document. A file attachment icon shows the place: Double-click this icon to open the file. A note is linked to the icon, so you can enter text explaining the contents or purpose of the file. This text later appears along with your name as a pop-up to the attachment icon.
Audio Attachment	Find this at Comment > Audio Attachment. Browse for the desired wav file and click Open. Replay it before attaching if you want to, and then click OK. Click the red Record button to create an “empty” wav file, and then click OK to attach it. A sound file attachment icon shows the place: Double-click this icon to start playing the file. A note is linked to the icon, so you can enter text explaining the contents or purpose of the file. This text later appears along with your name as a pop-up to the attachment icon.

Draw Tools	Use the tools in the drop-down list: Line, Rectangle, Pencil, Oval, Polygon, Polygon Line, or Cloud items to mark a place or area. They work practically the same way, so a note can be attached to a drawing object, it can be replied to and the object is listed in the Comments Panel.

Stamps can be considered as special annotation and markup tools with fully or partly fixed contents.

Annotations can be chosen to become part of a PDF prior to distribution with the command Flatten Document. This means the selected elements are transformed from annotations to document objects and are removed from the Comments Panel list.
