You can use also the Google toolbar as well. If you install Google toolbar,
my suggestion is *do not use the advanced features* ("page rank", for
example). They are kind of nosy. Otherwise it is fine, and will highlight. http://toolbar.google.com/privacy.html
Lastly, without any of the tools mentioned, if one does a Google search, and
the web page you select offers a Cached page, that will automatically
highlight your search term entries.
