That I don't know.  However, when I was using a keyboard with such extra buttons
I had

        usbhidaction -f 0 -c /home/smb/.hidconf

in my .xinitrc and

b132$ cat .hidconf  
Consumer:Consumer_Control.Consumer:Volume_Up                       1
   mixerctl -n -w outputs.master++
Consumer:Consumer_Control.Consumer:Volume_Down                     1
   mixerctl -n -w outputs.master--
Consumer:Consumer_Control.Consumer:Mute                            1
   /home/smb/bin/domute
Consumer:Consumer_Control.Consumer:AC_Home                         1
   rfirefox about:blank &
Consumer:Consumer_Control.Consumer:AC_Search                       1
   rfirefox http://www.google.com &
