If you type /cmdlist into the chat window, it will give you a comprehensive (and exceedingly-long) list of the commands that can be typed in, you may have to switch to the second, default channel to see them, however, as (if I remember correctly) the option that displays those commands is one of the checkboxes that is not, by default, selected for the primary Chat window.
Hope that helps,
(If that doesn't work, I have the complete list at home, and I will try to remember to put it up here, when I get home from work.)
Does anyone else think that was a weird sentence, using the words "work" and "home" too much? LOL
