Is it possible to add new keyframe types to blender using python?

Is it possible to add new keyframe types to blender?

No, there is no Python API to do that, these are hardcoded.

Is there an option to “hook” something to a keyframe? E.g. pausing the animation and waiting for a keypress before resuming? That would be super helpful to build next-gen Slideshows. :slight_smile:
