If you have done any animation in Flash, then you've created a motion tween on the main Timeline. This classic model is known to many students learning basic Flash skills. Adobe Flash CS4 Professional changes the way motion tweens work, and transferring your skills to the new way motion works takes a little bit of work. But it's not too difficult once you understand the fundamental change between motion tweens in previous versions of Flash (sometimes referred to as classic tweens) and those in Flash CS4.
If you have never created a motion tween before, or are new to Flash, you should examine the Animation Learning Guide for Flash CS4 Professional, which teaches you how to tween from the ground up. But if you're an experienced tweener and need to learn the fundamental differences between the two models to upgrade your skillset, then this guide is the one for you.
Note: You can still use the old-style motion tweens in Flash CS4 if you have to, maybe because you're actively working on some project you just need to finish. They're called classic tweens in Flash CS4, and you can access this option when you create a tween using the Insert menu or frame context menu.
