Apple Motion 4 - Manual (Page 541)

Note: To view the animation paths of keyframed objects, ensure that Animation Path is
selected in the View pop-up menu (in the upper-right corner of the main window, above
the Canvas).
When the Record button is off, changes you make modify the entire animation globally.
For example, if an object is keyframed to fly from the lower left to the center of the screen,
dragging the object to the right when the Record button is off moves the entire path to
the right.
Note: If you are positioned on a previously set keyframe, any changes you make modify
that individual keyframe rather than the entire curve, regardless of whether the Record
button is on or off.
Applying Movement to a Clip
Because moving objects onscreen is so fundamental to motion graphics, Motion makes
it especially easy.
