>I know sending ctrl-dwnarrow will open it, but I do not know how to determine if it is already opened or not. What I have done in the past to resolve this is to have the listbox have one size for closed and one size for opened:

>    THISFORM.List1.Height = 170
> ELSE  && close it
>    THISFORM.List1.Height = 23
