3-way slider control

[Paul Dupuis]

Hi all,

I am looking to see if anyone has a 3-positions slider control they 
might be willing to share. I need a control that has a "left, middle, 
and Right" positions (whatever they are called). Prefer horizontal 
orientation and resizable so I can adjust the size to the screen area 
where it needs to go, but I can resize graphics if needed.

Thank you to anyone (and everyone) in advance.
