Is there a way to select control points like selpt

I can use selpt and get all points, but wondered if there is a way to select only control points on a curve (for example)?
I can put some points on different layers to get it done, but looking for something like selcontrolpoint. —Mark

One way would be to bring up the SelectionFilter dialog and uncheck “Points” - then SelPt will select only control points… --Mitch
