volume key shortcut?

What's the best way to set up volume up/down shortcuts on a NEC MobilePro 780? I've got OKey installed but don't see a volume control button.

EDIT:
p.s. I see how to tie commands to keys in the registry...so if you know a "volume up" or "volume down" command, that would be helpful as well. Even a "how to run the volume control applet from a command" would be ok

I’m not sure about that but I wonder if it can plug into this program

Man, that's pretty rad itself. Might just try using that for a while.

If there's not a programmatic way to invoke it, I wonder if the source code is out there somewhere. Might be able to gen up something to do it.. I've been wanting to try and get a dev environment set up for this thing anyway.

Also unrelated note :
I highly recommend checking these out to see if they’re useful for you
The first link also has a different sound tray icon program

Awesome, thanks torch. (Feel like I've been saying that a lot lately!)
