Mark up documents the way you would on paper
Drag across a line of text and the highlight snaps to the words, line by line, just like selecting text. Switch to underline or strike-out for proofreading and contract review. Each mark is saved as a standard PDF annotation, so it shows up in the comments list of other PDF readers and can be removed there later.
On scanned pages, which have no selectable text, drag a box to highlight an area instead.
