Special-purpose keyboard buttons

[RD]

I'm wondering how to get emacs to see the "extra" buttons on my Dell 
keyboard, model SK-3185,

There are little round buttons marked with <-, ->, a little house, 
envelope, picture of a calculator, etc.

There are also player controls: stop, left, right, music notes, and a 
rotary knob for sound volume.

On Windows, the buttons do things, e.g.:

The music notes start Windows Media Player, and the player controls 
operate the Player.

The Envelope button starts mail.  The button with a picture of a 
calculator starts the calculator.
etc.

On Linux (Redhat 9), the buttons have no effect.

How can I find out what these buttons' names are?  Once I know the 
names, will I be able to bind them in emacs with ordinary global-set-key 
commands?

Regards,
Bob
