As per the SO question here (if you want to know how they did something there, take a look at the source, as per the hack documented here), I suggest that this (CW) question be used for testing purposes. Feel free to edit this question, add answers, experiment with deletion or markdown or what-have you.

Use this Markdown Editing Help reference as a guide, or this tome if you want to know every detail.

I'll take this question down if the community thinks that it is inappropriate, but if it is appropriate, we could have something like it pointed to in the FAQ and in the markdown manual.

This is a test edit.
