moving to different spaces and docks by pressing space bar and mouse point?

Hello,
i am new to this forum
I just formated my macbook pro and i just forgot what this program was....
the program basically makes the spaces with different docks, and i can assign a short key like "space bar" so when i press space bar and move the mouse point to right or left, top, bottom, then i move into another space with another dock..
does anyone know about this program? I thought it was "dockspaces" but it does not let me choose the space bar as a short key.


thanks

Was it Hyperspaces?
