Add objects to the Timeline overview
Just as you can drag objects (media and effects) to the Layers list or Canvas, you can drag objects to the Timeline. There are two ways to do this:
Add media to the Timeline layers list. This method is identical to the workflow for dragging media to the Layers list in Project pane.
Add media and effects objects to the Timeline track area. With this method, you can control how media is added to the project—inserted, exchanged with existing media, and so on—with a series of drop menu commands.
Additionally, you can set drag-and-drop preferences to customize how and where objects are placed the Timeline.
