Highlight text in PDF files


The text highlighting tools let you review documents electronically the same way you do on paper. The different pen-like tools let you highlight, underline and cross-out text, and then add text feedback to each one your markups.

Tip: The Underline Text tool's properties can be changed so that a squiggly line appears beneath highlighted text instead of a straight line
