Apple Motion 4 - Manual (Page 369)

Note: You cannot use Exchange with audio files.
To exchange an object
1 Drag an object from the Library or Media tab into the Timeline track area.
As you drag, a tooltip appears to tell you the frame number at which you are located.
2 When you reach the object you want to exchange, hold down the mouse button until
the drop menu appears.
3 Choose Exchange from the drop menu.
The old object is replaced by the new object.
Sequential
This drop menu option is only available when you are dropping multiple objects into the
Timeline. Sequential drops objects one after another in the Timeline. For more information,
see
Adding Multiple Clips to the Timeline .
Adding Multiple Clips to the Timeline
When you drag more than one item to the Timeline, the new objects appear in their own
tracks above any existing objects. This is equivalent to performing a composite edit with
a single object. A drop menu lets you choose whether the additional objects should be
stacked up as a composite, or whether they should appear one after another (sequentially).
Composite Sequential
To add multiple objects as a composite
1 Shift-select the files you want in the Library or Media tab, then drag them to the Timeline
track area.
2 When you reach the frame where you want the new objects to start, hold down the
mouse button until the drop menu appears.
3 Choose Composite from the drop menu.
The multiple objects are all edited into the project at the same point in time, each on its
own track.
