How does the Highlight Text work?
Apply highlight-marker style coloured rectangles to a PDF over text you want emphasised. Drag on the page to draw each highlight; the tool renders semi-transparent rectangles at those locations — yellow is the standard highlighter colour, with green / pink / cyan available for multi-colour annotation systems.
