Onion Skin

The term onion skin in computer graphics is also referred to as keyframe overlay. You can locate the onion skin under the canvas
panel. It is positioned on the left side of the show grid button.

Once the onion skin has been toggled, the effect will automatically be activated on the shapes and drawings within the canvas
panel.

With the onion skin toggled upon playback, you can see that the previous keyframe associated with the object will appear as a
translucent version of the element on the succeeding keyframes.
