Point button
If you paste the same block of time repeatedly, one block following the other,
you can create a looping segment in your animation. To create a smooth
looping animation, you need to exclude either the first or last key of the copied
block to prevent keys from doubling up at the ends.
The key to be excluded must be at the exact end time of the copied block of
time.
