For example, Once upon a time when I was playing with v3.xx:

If I need these 4 bones to move in a same rhythm, I just need to select all the kayframes of them at a frame, and click one of my presets, and do it again and again at other frames.

The presets are really useful for those characters with tons of bones.

Now I'm wondering how to do that in the Graph windows of v4.xx

I think there something I should do in the circle, but haven't figured out yet.
:think: :think: :think:

Nate ：

There are presets in 4.1 in the Curves view. Does that achieve what you need?

WOW！！！
Do you mean the Curves？Wonderful！
But it's still a beta now... is it good with the runtime "spine-unity-4.0-2021-07-02.unitypackage" ?
Or should I wait a little for the formal version?

Nate ：

It's almost out of beta, just wrapping up a few minor things.

You'll need to use the 4.1 runtimes with exports from the 4.1 editor:
Versioning - Spine User Guide: Synchronizing versions

COOL~
This one really helpful! Thanks a lot~
