The Keyframe Animator can be used to accurately control various object properties such as position, size, colour, volume, and zoom. Virtually every modification that can be made to an object can be achieved with the KFA.
The advantage of the KFA over the Movement control is that more accuracy can be achieved and more effects can be used at one time.
This page has links to various tutes which demonstrate the use of the KFA.
