Dooh! That's where I read them!

I don't entirely agree about your alternative suggestion, I would really like to see a brief list of the most useful codes instead of a note that they do work (which I could already know) without seeing which they are.

Thanks to eibwen's suggestion I've added it to my Free Nodelet, so I'll be able to find it in the future. Notwithstanding, I still think that it would be useful for most Monks to find it at the end of the editing page, near the list of approved tags.
