WARNING Don't turn off Snap Frames unless you have a reason to, such as the
need for more precise animation timing. If you do turn off Snap Frames and move
keys in Curve Editor you will create sub-frame keys, but they won't be noticeably
different in Curve Editor. In some cases, sub-frame keys can lead to animation
“popping,” or overly fast changes due to keys being too close together.

Snap Frames is on by default, so the following procedure only applies if you
have turned off snap frames previously.

NOTE This isn't an absolute necessity, but it makes it easier to see the
snapping action. You can also view the snapping in the track bar in either
Dope Sheet or Curve Editor mode.
2
On the Track View toolbar, turn on Snap Frames.
3 In the Track View Key window, select one or more keys.
