show open applications in Gnome Classic

[Rob Owens <rowens@ptd.net>]

I've been evaluating Gnome 3 "Classic" for the past couple hours, and I
still can't figure out how to display all the open applications.
Anybody know?

If the answer involves the Super key, could you also tell me either:

1)  How to change that

or 

2)  How to send the Super key in a Virtualbox session

Thanks
