1. Add Sticky Note and Text Box

Sticky Note and Text Box are widely used for annotation. You can add Sticky Note and Text Box wherever you want on the PDF page. Just choose Sticky Note or Text Box from the toolbar, drag your mouse over the PDF page to place the Sticky Note or Text Box. And then type in anything in the box. Next time if you want to view the Sticky Note on the PDF, just click on the yellow icon and the text box will appear. Different from Sticky Note, Text Box overlays the page contents, you can view the text directly when you view a PDF. The default colors of Sticky Note (yellow) and Text Box (red) both can be changed easily in Inspector.

2. Draw Line Annotations

You can add drawing and scribble imprints over the PDF pages. There are six shapes for you to choose. They are Arrow, Line, Rectangle, Oval, Polygon, and Cloud. All the shapes are listed on the toolbar. Or you can select them from the Annotate menu.

3. Add Free-hand Drawing and Links

Click Pencil button on the toolbar, and you can add free-hand drawings on the page. The Eraser tool can help you remove the drawings by Pencil. Click Link tool on toolbar, you can select an area to add URL or any page in the PDF file. When readers move the move over the area, they can click on it and link to the Internet or the page you set.

4. Markup PDF Text

You can apply a highlight color to specific selected text. You can use this to tool to mark words or sentences in a PDF document. Besides highlighting, you can also underline or strike through any selected text. All of these functions help you to mark the content easier.
