Is there are guide to formatting messages in forum posts?

I noticed that it is possible to put some formatting in our forum posts.

For example, a few people are able to get their links with descriptive (anchor) text instead of a URL. I found a few by trial and error. Can someone point me to a complete guide regarding what formatting options are available for us?

Update: I found an older post via Google that explains the codes. :)
Update2: Apparently these formatting characters are a subset of Markdown

Look at the wiki here where there are details of supported Markdown codes.
