"match type" "excluded words" etc.

[Slud]

Does anyone know how to use the fields displayed in this image from overture [secure.overture.com]?

It seems like setting "match type" equal to "broad" might allow for AdWords style matching. This would be a great boon to my Overture campaigns.

Am I dense? Have these options always been there?
