'Show all Workspaces' command for Meerkat NB Remix?

[gus.ke]

Hi all,
I'm looking to make a keyboard shortcut to mimick the function the Workspaces button in the new Unity dock, which shows all the virtual desktops at the same time. However, the keyboard shortcuts menu does not list this function and I cannot figure out what the command is. Could anybody shed some light on the situation for me?
Thanks!

i was looking for the same
and i foud this on the keyboard shortcuts wiki (https://help.ubuntu.com/community/KeyboardShortcuts):

Super + S Zoom out, show workspace switcher

then i wanted to translate it into a command and found about xdotool,
here:
Is there a command for "Workspace Switcher"? (http://askubuntu.com/questions/46613/is-there-a-command-for-the-workspace-switcher)

it works for me!
