Highlight annotations allow users to highlight information, specific text, or a paragraph on a document.
To add a Highlight annotation to the document, please click on the Annotations icon on the top toolbar, select the Highlight Annotation option from the dropdown menu and draw the annotation on the page by clicking and holding down the left mouse button while moving the cursor.
By clicking once on the placed annotation on the document, the Highlight Annotation Properties window appears where one can select the color of the annotation and enable the Border option to add outline to the annotation.
Please click on the Close button to finish editing.
