Use the Snap Keys options when you want selected keys to snap in time to the nearest whole time unit values or attribute values.

Depending on your keyframe editing style, you can also enable or disable the Snap Values to Adjacent Keys preference (Window > Settings/Preferences > Preferences). On by default, this preference sets neighboring keys with similar values to always snap to identical values as you edit keys. (See also Animation (Settings) preferences.)

To snap keys

1. Set the Snap Keys options. See Set Snap Keys options.
2. Do one of the following:
   • To select a single key, click the key in the Time Slider.

   The Current Time Indicator moves to the clicked position and the key is now selected.

   • To select multiple keys, -drag over the range of keys in the Time Slider.

   The range of keys is now selected and highlighted in red.

3. Do one of the following:
   • -click and select Snap from the menu that appears.
   • Select Edit > Keys > Snap Keys.

   If Time Range-All is on in the Snap Keys options, all keys for the current object are scaled. If Time Range-Start/End is on in the Snap Keys options, only keys between the specified Start and End times are scaled. If Time Range-Time Slider is on in the Snap Keys options, only the keys between the Range Slider’s Start and End times are scaled.

   Note

   If multiple keys can be snapped to the same value, those keys are skipped. A warning message indicates the number of skipped keys.

If you want to identify the keys on a curve that are not at whole time units, you can perform a search for all unsnapped keys.

To find unsnapped keys

1. In the Graph Editor’s graph view, select an animation curve.
2. -click the animation curve and from the menu that appears select Edit > Select unsnapped.
