328 Chapter 4 Using the Timeline
Timeline View Options
The lower-left corner of the Timeline contains several controls to customize what
elements appear in the Timeline.
Audio tracks are displayed in a separate partition in the Timeline. You can resize the
partitions by dragging the divider for each partition.
Zooming in the Timeline
You can zoom in and out in the Timeline using either the Zoom/Scroll control or the
zoom slider. Each lets you zoom in and out of the Timeline horizontally, showing more
or less time in the Timeline window. As you zoom in, you can see greater detail, which
lets you place objects with greater precision. As you move the zoom slider, the Timeline
remains centered on your current frame.
