laptop roller-ball use

[David Markert <dedalus ntr net>]

Hi,

Sorry if this is an easy one, but I couldn' find the answer.

I have a dell XP 4100CX laptop that I've just installed RH4.2 on.  The
install
went fine but I can't figure out how to get the roller ball on the
laptop to work.
I noticed that the default /dev/mouse file was soft linked to /dev/cua0
so I tried
the other cua?'s out of desperation but they didn't work either.

If there is not a solution for this, how do I find out the key strokes
to move
around in Metro?.  The only thing I can get to work in there is ALT-TAB.

TIA
