Re: Controlling Screen Brightness
Pressing F11 does not do anything.
"XF86MonBrightnessDown" is not recognised by openbox[1], you need to bind the key to an actual command[2] (eg, xbacklight) if you want it to do anything.
Alternatively, try using xfce4-power-manager, that can control the backlight via the function keys.
EDIT: typo.

Re: Controlling Screen Brightness
As noted above, XF86MonBrightnessDown is not an openbox action. It is the keysym you'd most likely want to use. In otherwords your rc.xml should include:
<keybind key="X686MonBrightnessDown>
<action name="Execute">
<command>
SOME COMMAND HERE TO REDUCE BRIGHTNESS
</command>
</action>
</keybind>What that command should be is up to you. Several options were referenced in the link provided in the very first reply you got in this thread. We had to take a tangent as you didn't seem to know how to bind a key to any of those commands. Now you have options for commands, and you know how to bind keys - you need to put the two together.
