Viewing options for the Motion Editor
Animate provides different viewing options for the Motion Editor so you can refine your property curves with greater accuracy.
Use the menu at the bottom of the Motion Editor to change the zoom level.
The vertical axis expands to show a more granular level of property values. Scroll up or down to see the top or bottom of the curve.
Click Zoom 100% to reset the Motion Editor to its default view.
Click Fit To View to expand the Motion Editor to fill the existing space on the timeline. Click the icon again (its name is now Restore View) to return to the default view.
