Assigning an action to to windows left button ("Super_L")

[Kevin Wilson]

Hello,
I want to assign the action "Hide all normal windows and set
focus to the desktop" to the windows left button ("Super_L").

I have Fedora 12 with Gnome and metacity. In previous Fedora releases,
like 8 or 8 (or maybe also 10/11, not sure ), I could do this by
simply going to system->Preferences->Keyboard shortcuts, and from there
assign Super_L to  "Hide all normal windows and set focus to the desktop"
simply by pressing the left windows button when asked to enter a key for this
action. With Fedora 12, this is not possible! When I press the windows left key,
(Super_L), nothing happens ! it stays blank ! I am **able** to enter a
combinatin
of keys, however. When I press "windowskey + M" I get Mod4 + M and then , when
I press the "windowskey + M" combination indeed I get a toggle of
hiding/showing
the desktop.

I tried configuring with gconf-editor and also with editing /etc/X11/Xmodmap
but it did not succeed.
I would appreciate any advice on it.

Regards,
Kevin
