After a little searching I have found that there is "a hotkeys daemon for your Internet/multimedia keyboard in X" that can be found in: Menu>System>Install/Remove Software. just search for "keyboard backlight" and select "hotkeys". The discription is as follows:
This program sits at the back and listens for the "special" hotkeys
that you won't normally use on your Internet/Multimedia keyboards.
The buttons perform their intended behaviors, such as volume up and
down, mute the speaker, control the backlight, launch applications, etc.
It has On-screen display (OSD) to show the volume, program that's being
started, etc.
It features an XML-based keycode configuration file format, which
makes it possible to define the hotkeys to launch any programs you
want.
Hope that helps.
