Repeating the instructions from above: Make.text bookarklet: place JS code between quotes in <a href="">make.text</a> to create the bookmarklet; click the <> button at the top right-hand corner to see the raw js to copy/paste. Save on a webpage, then drag the link to your browser's bookmarks.

Very handy to use in conjunction with something like the HackTheWeb Firefox extension, or the Karmatics Aardvark bookmarklet on which HTW was based: isolate the text on the page you want markdowned using HTW, or whatever, click the make.text bookmarlet -- presto! Instant markdown text.
