Copy/paste keyframes on a Roto bezier?

Software Natron
1

I’m animating a Roto bezier (animating the individual points, to be specific), and I would like it to loop, i.e. I want the keyframe data on the last frame to be identical to the first frame.

It seems like there is a way to copy/paste keyframes in the Curve Editor, but I cannot seem to make this work. I copy the first keyframe, then select the last keyframe, paste, but nothing happens. (Edit: I don’t know if this was happening before or not, but I quit Natron and re-opened my project, and when I try to paste it says “You must select a curve first”, but I can’t seem to be able to select the curve.)

(Second Edit: if I click on the curve it highlights, and I don’t get the prompt, but the Editor still says “No curve selected” at the bottom, and copy/pasting the keyframes doesn’t seem to do anything.)

Any ideas how to make this work?

When I right click the Curve Editor, there is a Loop option in the Predefined but I don’t know how to make it work. The Curve Editor made my Natron crash twice.

When I try to use that, I get a dialog that says “You must select a curve first in the view.” but I have no idea how to select a curve. Clicking on the curve doesn’t seem to do anything.
