animating Draggables

I don't think you can keyframe draggables (from title of post) - i have described how you can use blends instead in a recent response. But to turn on keyframing, in the timeline view, hover over the property name and a little keyframe icon appears next to it. Click to record that value and turn on keyframing for that property. The icon should remain on afterwards. You can either record property values live or keyframe them, but not both.
