Spline Editor - Transform Keys

While animating a "Transform Node" I noticed that the keys for Center X and Center Y are combined into a single key called Center(Path1)/Displacement. Is there any way to separate the x and y values into their own curves so that I can animated each value separately? I need to have independent control over both channels.

Side note: What does the "Lock Symbol" mean for certain key frames?

Thanks
Josh

Anyone have any info on this issue? I would really love to figure it out and I can't seem to find any answers other places.

With the animated node selected, right-click in the Viewer, and point to Path1:Polyline > Convert to XY Path.

I think, but I'm not 100% certain, that the lock icon means that you can't change the keyframe's value, only its time index.

Thanks so much Bryan, I'll give it a try

Great tip, I've been looking for an answer to this one myself, thanks!

Thanks Bryan, but WHY can't I change the value? I've got a simple transform node that I'm keyframing it's displacement on, and I continuously get locked keyframes I can't deal with anymore..
I think it occurs when there's overlap of similar keyframed icons on the spline viewer.. but visual overlap of a keyframe icon indicator on a timeline seems bound to happen, thoughts?

Thanks in advance!
