Bad advice, it needs updating

I’m using 2.80

Nope, there is no “Bake menu”, there is no “clear constraints” menu.

Wrong again, after literally only baking a curve into a single keyframe, this option is greyed out.

The advice for converting a baked curve to keyframes needs an upgrade.

Are you looking for “bake action”?

I’m looking for more the opposite of that.
