The time ruler visually represents the time dimension of a composition, a layer, or a footage item. In a Layer or Footage
panel, the time ruler appears near the bottom of the panel. For a Composition panel, the time ruler appears in the
corresponding Timeline panel. The time rulers in different panels represent different durations. The time ruler in a
Layer or Footage panel represents the duration of the contents of that panel; the time ruler in the Timeline panel
represents the duration of the entire composition.
On a time ruler, the current-time indicator indicates the frame you are viewing or modifying.

or 1:00 to go forward one second. Precede the value by the minus sign (-) to go backward. For example, enter +-20
to go backward 20 frames or +-1:00 to go backward one second.

composition, or the beginning or end of the work area.
Jeff Almasol provides a script that creates a panel with controls for moving the current-time indicator to different times
in the composition. The panel provides buttons for jumping a specific number of frames forward or back from the
current time, as well as buttons for capturing different times and jumping to them easily. For more information, go to
Jeff Almasol's redefinery website.

Choose a viewer to always preview
Designating a viewer as the default panel to preview is especially useful when you have a Composition viewer that
represents your final output and you always want to preview that viewer even when you're changing settings in other
panels.
The panel that's set to always preview appears frontmost for the duration of the preview.
