Keyframe Editor Control Buttons
In the lower-left corner of the Keyframe Editor, five buttons provide additional control
over the Keyframe Editor window: Snapping, “Show audio waveform,” “Fit curves,”
“Clear curve list,” and “Take/Show curve snapshot.”
Snapping: When snapping is turned on, keyframes snap to other keyframes, markers,
grid points, and other snappable items.
Show audio waveform: Turns on the display of audio waveforms for the selected
object.
When “Show audio waveform” is turned on and the project contains at least one audio
file, a pop-up menu at the bottom of the Keyframe Editor allows you to view the
waveform of the master audio track, or any individual audio track in the project.
Fit visible curves in window: Automatically scales the graph both vertically and
horizontally (in time) to include all of the keyframes of your active parameters.
Clear curve list: Empties the parameters list. This control is only active for custom
curve sets.
