Sorry, but you’re on a very specific wordpress plugin support. It is not the place for such basic question (what are the short codes). BuddyPress doesn’t provide shortcodes.
This plugin is not common, and not the most easiest to use. The forum is maintained by volonteers, and unfortunately not by profesional teachers. If you are very new to BuddyPress, and apparently to WordPress too, you have to do your homework.
You can get starter information on both codex. For BuddyPress you get access to appropriate documentation via the above menu bar.
For WordPress, and specifically your question, click here.
