can't revert back to bezier interpolation mode

When I change an f-curve’s interpolation mode from bezier to linear, it seems I can’t change it back to bezier. I click and it just doesn’t happen. Bug?

  1. Where are you trying to do this from?
  2. Make sure you’ve got some keyframes selected. This is now a per-keyframe setting

My problem was that I was selecting the last keyframe. Apparently with the new system each keyframe controls the segment following it. Problem solved.
