Sometimes, at work, we have terrible internet latency. This makes every page loaded count. I use DuckDuckGo as my primary search engine, and sometimes poor caching and latency combine to create a few seconds between starting to load the page and entering my query. So I whipped up a little Bookmarklet to bring up an equivalent search box, instantly. Hooray JavaScript! (The only time I'll ever say that...)
Here, drag: DDG
Works wonderfully as a hot-key, e.g., cmd-2 in Safari as the second link in my Bookmarks bar.
