Cube desktop changer in KDE 4

view full story

http://forums.opensuse.org – In GNOME on 11.1, I could hold down Ctrl - Alt and then drag with my mouse to "open" the cube. Is there a similar mouse combo for KDE 4 on 11.2? I know of the Ctrl-F11 key, but since I switch windows with the mouse, I would always have to take my right hand off the mouse to hit the F11 key...? A mouse drag is way more intuitive to me...
