I just found out, after some maddening minutes, that you can also delete keyframes from Fusion.
Go in the Keyframes tab, then to select a single keyframe (or multiple) you need to:
- hold CTRL,
- click inside of the row where the keyframe is applied. The row will become less greyish
- keep holding CTRL, then point the mouse slightly to the left of a target keyframe. The mouse pointer indicator will flip, as per when you select some text. Hovering on existing keyframes will make them become yellow.
- Then, you can click that keyframe. A selected keyframe appears as light blue.
You can then move the individual keyframe by dragging it, or press delete to delete it.
REALLY INTUITIVE. Made a GIF to help others:
