Yellow Dog Linux

Hello, before anything else let me just say that I am a complete newbie
to YDL and Linux in general.

I have YDL installed on the PS3.

I have but one simple question. I accidentally erased the main tool bar
on destop, now all thats visible on the desktop are the folders.

I was wondering if someone can tell me how to bring back the
tool bar that has all the necessary locations: Applications.

any help would be appreciated, thanks.
