Getting special keys to work

On lubuntu-rc.xml I do:

<keybind key="XF86Display">
      <action name="Execute">

*lxrandr* deals with additional monitors, you just enable them an apply.

I'm not sure what commands you can execute to sleep and hibernate, but you
can control radio with *rfkill*. I'm not sure if those commands really
require root access, but on that case you can do a: *gksu command*

Hope that helps! To test the shortcuts without restarting all the system
you can restart only openbox: *openbox --restart*
