Betty,
I remember now (prompted by Brad). Go to CO at any time and type "/help".
That will give you a list of the available commands with a one-line
summary. I have that next to my computer on one of those clipboards that
stands up so you can type from them (I'm sure they have a more elegant
name, but right now it is eluding both me and my wife).
Interestingly, the one command it doesn't list is "/help" which is why I
couldn't remember it.
