I am currently using Ubuntu 15.10. I need to highlight some sentences and/or paragraphs for easy searching but I can't find any option for this in the "Document Viewer" which is the default application for pdf files.

Document Viewer DOES actually support annotations and highlightings in PDF files (not in other formats). Just click on that notebook like button and you'll be able to annotate and highlight text.

13@GStav You can right click on the highlighted text and select
Remove annotation
. You can also right click and selectAnnotation properties
and change colour etc. – consuela Jan 29 '18 at 13:43 -

Try Mendeley (https://www.mendeley.com/)! It does the work like a charm!
In fact, Mendeley is more than a PDF-reader. You can use it to organize your docs and references.

Document Viewer doesn't support highlighting install another application such as FoxIt Reader. I prefer foxit because it's simple to use and if you install on Windows, Mac or mobile keep the highlighting and attachments.
To install foxit reader :
- Open Foxit website.
- Click "Free download" and it will detect operating system then click "Download".
- Extract the file you downloaded.
- Double click the .run file and install.
