Apple Motion 2 - Manual (Page 292)

292 Chapter 4 Using the Timeline
To delete a layer or object track:
1 Select the layer or object in the Layer list.
2 Press Delete.
You can also Control-click an object, then choose Delete from the shortcut menu.
All of the operations just described can also be performed with multiple tracks. For
example, rather than just moving one object from Layer 1 to Layer 3, you can select
two or three objects within Layer 1 and move them all at once.
To select more than one object or layer track:
m Command-click each of the tracks in the Layer list that you want to include in your
selection.
Splitting Tracks
Occasionally you may want to divide a single object into multiple objects. You might
do this if you want an effect to apply to a portion of a clip and ignore another part, or
you might want an object to change layer order midway through, to create the effect
that objects are moving in 3D space. Splitting tracks allows you to turn one object into
multiple pieces and then manipulate each segment of the object on its own track.
To split an object track:
1 Select the bar or track in the Layer list for the object you want to split.
2 Place the playhead on the frame where you want the split to occur.
3 Choose Edit > Split.
The object is broken into two pieces, each positioned on its own track.
