app.project.item(index).layer(index).propertySpec.keySpatialAutoBezier(keyIndex)
Description
Returns true if the specified keyframe has spatial auto-Bezier interpolation. (This type of interpolation affects
this keyframe only if keySpatialContinuous( keyIndex) is also true.)
If the property value type is neither TwoD _SPATIAL nor ThreeD_SPATIAL, an exception is generated.
Parameters
keyIndex The index for the keyframe. An integer in the range [1..numKeys], as returned by the addKey or nearest -KeyIndex method.
Returns
Boolean.
