One of my favorite features of Chrome is that if you start to type "amazon.com" in the URL bar, and then hit Tab when it autocompletes, it switches the URL bar to an amazon.com search bar. I don't think I've typed anything in the actual search field of amazon.com in years.
This also works with the space bar, as well as the tab key. I find pressing the space key to be a bit more fluid when I already know what I intend on typing next.
