Highlight PDF: what you need to know
Reviewing a contract, studying a paper or flagging changes for a colleague is easier with highlights. Choose the Highlight tool and drag across any line; add arrows, boxes and comments where something needs attention.
The highlights are saved into the PDF, so anyone who opens it sees the same marks.
