Use the Text highlight tool  to add a coloured, semi-transparent highlight around selected text. Like other annotations, the highlight has an associated pop-up note window.

  1. Select the Text tool  from the toolbar.
  2. Select the text you wish to highlight.
  3. Click  in the Formatting toolbar to highlight the selected text
    or press Ctrl+G.
  4. To open the associated pop-up note window, activate either the Text tool  or Hand tool  and double-click the text.
Notes
  • Text highlights are annotations that sit on top of the PDF page like other annotations. They do not track the text to which they apply which means that if you edit the text on the page after highlighting, the text may move with respect to the highlight.
  • A similar result can be achieved using the underline facility – this will track edited text but does not have an associated pop-up note window. See Underline & Strike-through.
