How can I highlight PDFs?
Is there a software like Mac's default viewer, that allows you to annotate and highlight PDF documents?
Thanks in advance, Marco
This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
Okular has support for highlighting and annotating PDF documents. Also see http://okular.kde.org/faq.php#HowcanIannotateadocumentandsendittoafriendcollegueetc
"Xournal supports annotation of PDF files through the Poppler library; PDF files, much like paper styles, are loaded as an immutable background image."
