Timeline Layers List
The left side of the Timeline is the Timeline layers list. Like the Layers list in the Project
pane, objects appear in the project hierarchy categorized into layers and groups. The
Timeline layers list contains many of the controls as the Layers list in the Project pane:
Activation checkbox: Turns the visibility of an object on and off. When the object visibility
is off, you can still modify the objects parameters and manipulate its onscreen controls.
Name field: Identifies the object by name. (This column is identical to the Name field in
the Layers list.) To edit the name, double-click the text area of an object, enter a name,
then press Return. In projects that contain a camera, the Isolate button also appears in
this column.
Isolate button: Appears for a layer, group, or camera in a project that contains a camera.
The button has an active and inactive state. Clicking the Isolate button for a layer or group
sets that object to its original face-forward orientation (so you can apply a mask, for
example). Clicking the button again returns to the previous view. Clicking the Isolate
button for a camera takes you to that camera’s view.
Note: When a group or layer is isolated, the name of the item replaces the current camera
listing in the Camera menu (in the upper-left corner of the Canvas).
Mask icon: Appears when a mask is applied to the layer or group. To turn off the mask,
click the icon. A red slash appears through a disabled mask’s icon.
Behavior icon: Appears when a behavior is applied to the layer or group. To turn off the
behavior, click the icon. A red slash appears through a disabled behavior’s icon.
Filter icon: Appears when a filter is applied to the layer or group. To turn off the filter,
click the icon. A red slash appears through a disabled filter’s icon.
