First: thank you Omar and Wayne for your concern. I accepted the script to run but it didn’t change the connected line between the keyframes. But I went on the exercise (because the animation was working) and encountered many difficulties in understanding why I was doing some actions: that can be a mix of my (not good enough) English and some «Blender logic» I haven’t catch yet… (Like: how can a linear interpolation can produce a parabolic path? Does the strategy «e minus 2», in order to remove frames, require a numpad to work? I dont’ have one and I’m on Mac. And why do I have white keyframes and yellow keyframes?) …I think I will take some rest now!!!
