* Copy/Paste operators for F-Modifiers Available in Graph and NLA Editors. Use the Copy/Paste buttons beside the 'Add Modifier' buttons. Copy copies all the modifiers of the ACTIVE F-Curve or Strip depending on the editor. Paste pastes modifiers from the buffer to all the selected F-Curves or Strips, adding the new modifiers to the ends of each list. * 'Stepped Interpolation' F-Modifier This modifier holds each interpolated value from the F-Curve for several frames without changing the timing. This allows to preview motions 'on-twos' for example without altering the timing, or having to go through setting heaps of keyframes. In this case, Andy wanted to use this for CG <-> StopMo.
