SUN type 6 keyboard

Here a newbie,

Can anyone please help me with this, it has probably has been asked over 
and over again but I CAN't find it !

How do I get the SUN special functions located at the left hand side of
the keyboard, like
(COPY, PASTE, FRONT, OPEN etc etc) on the type 6 sun keyboard to work
on my SUN ULTRA sparc 10

I'm using suse distribution 7.3 for sparc architectures
