Question

I’m trying to animate some UI elements, and I can add tracks of the properties I want to animate and add keyframes, however I want to edit the animation curves (bezier curves), but the curve editor button is greyed out/disabled.

Why is that, and how do I enable it?

I’ve seen a reddit post with this exact question, but the only answer there was “When you add a keyframe in the menu select Bezier curve. Only those can use the curve editor”.
But when I right click and add a keyframe, it just adds the keyframe, I don’t see any option to select “Bezier curve” when adding a keyframe.

Nevermind, I figured it out…
The bezier option is not when adding a keyframe, but when adding a track. There is a “Bezier Curve Track” option when adding an animation track.
