How to change the shortcut to adjust brightness?

Yes I did it again! Thanks to myself!

1) Install XDoTool and Compiz

sudo aptitude install xdotool compizconfig-settings-manager 

2) Open CompizConfig Settings Manager

ccsm  

3) Go to commands and add this lines:

xdotool key XF86MonBrightnessUp  

xdotool key XF86MonBrightnessDown

I hope I enjoy ;-)
