Animation and keyframes
Last updated 12/21/2009
Show Animated Properties Displays animated properties of selected layers in the Graph Editor.
Show Graph Editor Set Displays properties that have the Graph Editor switch selected. This switch is next to the
stopwatch, to the left of the property name, when the stopwatch is active—that is, when the property has keyframes or
expressions.
Note: Aharon Rabinowitz provides tips for using this control and showing the audio waveform for a deselected layer on
the
Creative COW website .
