Keyframes can be set directly to CV and Vertices,
but the setting becomes complex because there are a lot of numbers,
or you would forget which group you have set keyframe.
You can make groups with Cluster Deformer.
This example is NURBS modeling.
Select CVs.
In Animation Menu Set
Deform > Create Cluster
The cluster is displayed as
C
The groups are made by considering how to make animation.
In this example, 3 groups are made.
If necessary, move the pivot point of the Cluster.
Set keyframes to each Clusters.
In this example, the cluster Z scales are animated.
