Motion Tweening in CS4

Flash CS4 has a new Motion Tween feature that's object based, instead of timeline-based. This is very much like the tweening in After Effects. Depending on where you are in the timeline and what object you have selected, you can right-click (control-click) on the timeline and choose Motion Tween. Then you can change the properties of that object in the properties panel. Move to another spot on the timeline and continue to change the properties. All of the tweening is done for you.
