I'm having mouse troubles, I have a serial mouse with a mouse wheel (set
to port 0).

The left and right button are working well, but the middle mouse wheel is
having troubles :
mousewheel up: cursor goes a little up and to the left.
mousewheel down: little to the right.
click mousewheel/middle button: little to the right + right click menu.
Worse yet when I shift+right click, the copy/paste menu flickers on and
off and I can't choose any of the commands.

I did some debugging (man mouse) and I noticed that when I use "echo
buttonmap 132 > /dev/mousectl" I can use the copy/paste menu but I
obviously lose the windowing menu...

* Hopefully someone here will guide me on how to fix the mouse
functionality (the mouse works on other systems so its a plan 9 issue
rather then an hardware issue), but I'm also interested on re-programming
the shift key in rio so to switch between buttonmap 132 and 123, this way
I can still have some functionality from that machine if all else fails.

Thanks,
