How to change object's origin to cursor?

How can I change the object’s origin to cursor? F9 doesn’t work for “center new” as in 2.49. I’m trying for an hour and I can’t find it. I wonder why it should be so hard to find it.

or the Origin button near the top of the toolshelf
or the Object / Transform menu entry
or Spacebar, search for origin

Thank you very much, that was lightning fast! :slight_smile:
