Moving Keyframes in Motion

I just happened upon a strange quirk of Apple Motion 3.0.2. Maybe it's existed all along in previous versions but I just found it. When you keyframe a behavior, in my case keyframe the speed of a Motion Path, and move the behavior on the timeline the keyframes don't move. They stay rigid to the time of their creation. This causes problems when you want to move a layer with a behavior to a different spot on the timeline because all that beautiful motion you just created has to be redone.

But, I found a work-around!!! Simply slide the behavior to the new time you want in the timeline. Place the play-head on the first frame of the moved behavior and then select the clip the the behavior is attached to. Simply press the letter "i" to set a new In-point. The clip should start at the same point as the behavior. Now go to the end frame of the behavior, be sure to left arrow key back on frame select the clip again and press the letter "o". This sets the Out-point of the clip to the same as the behavior.
