How to set a new key point through the timeline interface?

When I move the timeline play head either manually or because of hitting the play button, how do I know create a new key point for any of the GUI elements?

I know I can do a two finger click on the timeline. But this needs to be done slightly beside the timeline header line and then moved back in to position.

Is there a way to auto set a keypoint at the play head position of the gui that gets manually changed?

and along the same lines, how do I delete a keypoint?

There is still no automatic way for adding keyframes when changing a parameter, although it is in the top of the TODOs. It can be done by adding a listener to a parameter and then adding the keyframe in the listener callback but it is a bit cumbersome. I think it is easier if I just add this feature.

To delete just select a keyframe and press the backspace key.

Hi, no, there is not such thing! I was asked already for that feature, and I'll implement it soon. On the meanwhile you can

I've seen this randomly happening . I'll try to recreate it, I think I know what the problem is. Thanks for the video
