The latest version of google toolbar is awesome. The basic use of Google Toolbar (latest version) allows suggested hits. for example, say you wanted to do a search for something like "internet forum". If you type at a rate of about 2 letters per second (slowly) you'll see suggested popular hits. Like hit the letter 'i' and it comes up with the most popular searches that begin with letter i. type in the next letter so you now have "in" - it first tells you how many centimeters (see pic) and then gives you the best/most popular serach queries starting with the letters "in". It continues along from there.
Another thing is that your own search history takes priority. For example, something like "injuries" isn't among the most popular search queries that start with "in", but if you have searched for "injuries" before, then that will take presedence. Frickin awesome program.
