Waldo: Search the JavaScript Object Model in under 1 KB

Here’s a tiny util that you can save as a bookmarklet and use to crawl the JavaScript object model of any web site. Waldo (thanks to @shinypb for the name!) lets you find and inspect instances by name, type or value, and it can be easily customized to add additional tests.
