The object time line represents the evolution of your object throughout time, showing you small previews of the key frames and of some intermediate steps.
The first time you open the Key Framer with an object, only the first Time Line box (Frame) is displayed, with the current appearance of your object.
You will store the modified object in empty boxes to build the animation key frames sequence. We will explain this in detail below.
The Object time line also contains a Trash icon, which allows you to delete key frames, a page number selection box, as well as a slider which is useful for browsing the Time Line pages (like the Catalog).
