Sun keyboards have keys for many neato things, including volume up/down/mute, 
contrast, etc. I didn't know one of these was a degauss key. :) 

In Solaris, the "special keys" on the keyboard are controlled via the 
speckeysd/xspeckeysd daemon (or something like that? I can't find it now). Note 
that they only have an effect on machines with hardware that will support it -- 
e.g, you can change contrast with them on a Sun Voyager, but probably not much 
else.

You might start with the Solaris docs on the daemons, I seem to recall they've 
got some info in there.
