How to highlight different keywords Simultaneously in a single webpage?
like in a set of paragraph I want more than one keywords to be highlighted.
e.g. "Law enforcement in many European countries served warrants at the same time, seizing servers expected to contain more evidence about the leaders of the ZeroAccess crime ring, which was devoted to "click fraud."
In this paragraph I want to highlight "enforcement" and "contain" simultaneously.
I am sorry I didn't frame my question correctly. I want the highlights automatically by typing the keyword in search box but many words simultaneously.
You may also suggest me any add-on.
