Rated 5 out of 5 stars

Highly useful. If I might suggest an additional (optional?) feature: a kind of auto-detect which examines pages for input boxes and makes sure that the cursor is placed into the first one automatically, eliminating the need to use the shortcut. It probably would not work on every page, and sometimes it would anticipate the user's intentions incorrectly, but nonetheless it would be an enormous timesaver, considering how many webpages consist of little than a single search box.
