Oblijiphetamine

It told me a button/key combination to type in to get it back, but I didn't see it in time. Can someone tell me what it was or how to get the toolbars back?

It then says that the app may appear frozen, and it says sending to server, try 1. Then it does nothing, and closes. I don't know what to do and I know nothing about computers. Please, someone help me. I really want to go on Second Life. I just downloaded Second Life to my laptop. [I previously had an account on another computer]
