Underline, highlight, and strikethrough are annotations that are placed on top of the text. This means the text doesn't actually change as you underline it, instead, an underline element is added to your document.
Note: These features are available only in PDF Suite Professional licenses.
- Open the Edit tab.
- Switch into Edit Mode.
- Select the text that needs to be annotated.
- Choose the feature you want to use.
- Select the color you want to use.
You can add a comment to any annotation you've added to your PDF.
You may have noticed that deleting the text you've annotated will not remove the annotation. You'll also have to delete that element.
- Right-click on the annotation.
- Choose Remove.
