As someone who prides himself on being a reliable source of useless trivia, I tend to search for pretty obscure stuff. A lot of times, the pages I find have more text than I want to wade through. Using the Google Toolbar, though, it's pretty easy to see what I'm looking for. My search terms show up as clickable Word Find buttons in the Toolbar, so I can quickly find where they appear on the page (clicking on it repeatedly takes me to each instance). This came in handy when I needed to figure out what species made a jumping bean hop around.

Try it out yourself.
