The Timeline is where all of the motion in an Edge composition is orchestrated. The Timeline itself shares concepts and constructs from other Adobe applications, most notably Flash Professional and After Effects.
The playback controls in Edge are all grouped together to in the upper left corner of the Timeline panel. These controls allow quick access to many of the playback options available through the Timeline.
The time in Edge is measured in standard decimal timecode format:
mm:ss.ddd, and this is how it is displayed in the Time control. As the Playhead moves along the Timeline, the information in this display is updated accordingly. A user can scrub the control to the left or right to adjust the current time, or simply click upon it, making it editable.
