Apple Motion 3 - Manual (Page 363)

Chapter 4 Using the Timeline 363
You can assign different colors to different types or markers and create marker groups.
For example, use green to label all audio markers or gold to identify all temporary
object markers.
You can add two types of markers: project markers and object markers. Project
markers are fixed to a specific timecode value in the ruler. Object markers are attached
to an object and move around as you move the object. Object markers appear only in
the Timeline. Project markers appear in the Timeline, Keyframe Editor, and Audio Editor.
Note: Project markers are indicated in the mini-Timeline by a fine green line. For more
information on the mini-Timeline, see “
Mini-Timeline ” on page 61.
To add a project marker:
1 Place the playhead on the exact frame where you want the marker to appear.
2 Check that no objects are selected, then do one of the following:
 Choose Mark > Markers > Add Marker.
 Press M.
 Control-click the gray marker bar above the ruler in the Timeline, then choose Add
Marker from the shortcut menu.
