Working With Regions
Sometimes you may want to make changes to a range of frames, known as a region.
You might do this to cut or copy a section of time to remove it or move it to a new
position in your project. Regions do not have to align with object edges in the
Timeline. You can create a region that begins midway through an object or one that
includes empty frames beyond the edges of objects.
To select a range of frames:
m Command+Option-drag in the Timeline.
A light blue band appears over the selected frames.
To expand or contract a region:
m Position the pointer at either edge of a region to modify its end point. Click to the right
to make it longer or to the left to make it shorter.
Selected regions ordinarily apply to all tracks in your Timeline. However, sometimes you
only want to select one or more tracks. This allows you to make complex selections
across multiple layers and tracks.
