I am experimenting with Poser features trying to get more familiar with it.   I am currently on animation.  I am trying to copy keyframes to make a sequence, but it doesn't work.  I drag to select the keyframes to copy, hit CTRL-C, select where I want them to start and hit CTRL-V.  But all that happens is that Poser adds a beginning and ending keyframe to any parameter not already keyframed, sets the to spline curve, and does not paste what I wanted.  In fact it does absolutely nothing with what I copied.  

So far I have tried the copy/paste keyboard shortcuts, the edit menu, and even tried every combination of SHIFT/CTRL-click and drag that I can think of, but I get either the same results or Poser just moves the keyframes.  :(
