Highlight and annotate a paper
Highlight or underline text, add a note to a highlight, and change or delete it.
- Select text in the PDF.
- In the toolbar that appears, pick a colour (yellow, green, blue, red or purple), or choose "Underline".
- Type a note in "Add a note to this annotation…" and press Enter to save. Shift+Enter adds a new line.
Right-click a highlight, or use "More actions" on its row in the "Annotations" tab, to "Edit note", "Change colour", "Copy quote", "Ask Assistant" or "Delete highlight". After a delete, "Undo" is available for a few seconds. The "Annotations" tab lists every highlight and can be filtered by colour.
Highlights made by other members are visible to you but only they can edit or delete them. Highlighting needs the PDF, and does not work on scanned PDFs that have no text in them.
