Lubuntu minimize all show desktop keyboard shortcut?

Is there a show desktop (also known as minimize all) keyboard command in Lubuntu? I looked around in lubuntu-rc.xml, but I didn't have any luck.

If there is one, and it's a Super key, then is there a way to change it? I'm using a Model M keyboard, which is pre-Super key.

Solution 1:

In 13.04, "show desktop (also known as minimize all)" is found in ~/.config/openbox/lubuntu-rc.xml:

<keybind key="W-d">
  <action name="ToggleShowDesktop"/>
</keybind>

Try changing W-d to some other combination. Only you know which combinations are free on your system.
W = window/super
C = control
S = shift
A = alt
