I can’t seem to add a keyframe to an IPO (in IPO window) unless I do it in the 3d window, this of course adds a extra keframe to all the current IPOs for that object. I am using 2.37a.
And why can’t I add a keframe to the back end of a curve (on the extrapolate end), should I extend that somehow?
When I (G)rab a keframe how do I lock the direction that I want to move it, i.e. Horizontal or Vertical?
