A friend of mine pointed me to this message from one of the Xorg lists. I
have not yet had time to test it, and it will probably be a couple days
before I do. Hope this helps everyone out. -George

No longer required, actually harmfull now.

man mouse (default was wrong, have commited that now):

       Option "ButtonMapping" "N1 N2 [...]"
              Specifies how physical mouse buttons are mapped to logical
              tons.   Physcial button 1 is mapped to logical button N1,
              cal button 2 to N2, and so forth.  This enables the use of
              ical    buttons    that    are    obscured    by
              Default: "1 2 3 8 9 10 ...".

So if you want to get buttons events 6 and 7 with physical buttons 4 and 5
you want
        Option "Buttons" "5"
        Option "ZAxisMapping" "4 5"
        Option "ButtonMapping" "1 2 3 6 7"

But as mice with two wheels are getting more available now, applications
might be configured to use buttons 6 and 7 for horizontal scrolling
soon. You might want to use the default configuration and configure
applications to use buttons 8 and 9 for button actions.

Though it is largely undecided right now whether the default like it is
now is a good idea, or whether other buttons should be reserved for the
secondary wheel.

This is because due to default ButtonMapping you get 4 more buttons than
configured. But you don't want to use xmodmap any more.

No. Different thing.
