Groups pane
In the Animation Trigger window, the Groups pane lets you create, delete, and synchronize a triggering group. A triggering group is a collection of motion clips and triggers. The Groups pane consists of the following options:
Keep Active When Closed
The Keep Active When Closed option lets you trigger motion clips in the Animation Trigger window even when this window is closed.
When the Keep Active When Closed option is enabled in the Animation Trigger window, the equivalent Animation Trigger option is enabled in the Viewer window and all keyframe animation features are disabled.
Create button
Creates a triggering group. The Animation Trigger window must contain at least one triggering group for the other features in the Groups pane to be available.
Delete button
Deletes the selected triggering group.
Sync button
The Sync button lets you continue playing from the first motion clip of the triggering group.
