The body of the graph displays the keyframes and curves of active parameters (those in
the parameters list). Each curve is a different color, although some colors are duplicated.
Control Buttons
In the Keyframe Editor, several buttons provide additional control over the Keyframe
Editor window:
Choose Background Audio Waveform: A pop-up menu that lets you turn on the display
of audio waveforms for the selected item in the background of the graph. This lets you
line up an effect to take place at the same time as an event that occurs in the audio. If
there are multiple audio tracks in the project, you can use this menu to view the waveform
of any individual audio track in the project, or the master track.
Display Waveform pop-up menu
Clear Curve List: A button that deletes all items in the parameter list from a custom set.
Fit Visible Curves in Window: A button that scales the curve graph to show all keyframes
of active parameters. There are times when the values of keyframes exceed the vertical
resolution of the graph. For example, as you stretch a keyframe, you can drag it so far
that you force the window to scroll.
