Reading a long report, a contract or lecture notes is easier when the important lines stand out. The Highlight text tool outlines every line of text on the page; click a line and it is highlighted in the color you picked. Marks are separate objects, so you can remove or recolor any of them later.
For scanned documents, which have no text layer, switch to the Highlighter in the Draw menu and drag across the words. Both kinds of highlight are written into the page when you download, so they appear in every viewer and in print.
