Retrieves the animation channels from requested parms and creates a sop geometry that can be modified. Each parm, will get its own curve, with the x coordinate being the frame number and the y coordinate being the keyframes value.
The resulting mesh represents a point for every frame of the playbar in the parm. Each point has a parm attribute, showing the link to the original parm.
Once modified, you can use the Set Parm Keys node to update the animation channels.
