Ask HN: Share Your Favorite Bookmarklets

Here are a couple bookmarklets I find myself using often:

Post current web page to HN

   javascript:window.location="http://news.ycombinator.com/submitlink?u="+encodeURIComponent(document.location)+"&t="+encodeURIComponent(document.title)

Find Archive.is link

   javascript:window.location="http://archive.is/newest/"+document.location
