The PDF reader "Okular" contains a seemingly smart functionality for
this purpose. It is the same package which is being pointed at the
page you have found yourself:
http://askubuntu.com/questions/1529/how-can-i-highlight-pdf

To annotate, etc.:open the PDF document in Okular
tools > review or F6.
You can make text annotations "inline" or next to the text.
Additionally, you can make yellow highlights, straight yellow lines,
polygons, put stamp symbols, underline the text with a black line and
make cyan ellipses.
Okular is a typical KDE/Kubuntu package. However, it is also possible
to install it from the repository in any other *Ubuntu distribution.
Respectfully yours,

Bas.
