How to increase the number of gnome-shell workspaces in F15?

[Joachim Backes]

Hi all testers,

I have problems to increase the workspace number of gnome-shell in F15: 
I found some advice in the forums: "pressing Activities" will show a +/- 
icon on the bottom of the desktop where the number of desktops may be 
managed.

But I don't see such an +/- icon.

Any other solution?

Kind regards
