What is the difference between Swap Buffer and Snap Buffer in Graph Editor?

Hi! everyone,

Maya 2024 Graph Editor on Windows 10. Select a key and right-click to open the options menu, at the bottom you will find the Swap Buffer and Snap Buffer options.

Select one of them and when you move the key, you will see the ghost before you moved the key. Both have the same effect.

At least I could not see any difference.

Please let me know when and why they exist and how to use them.

Thanks,
