=== Creating a stop-motion keyframe ===

A "stop-motion," or "hold," keyframe is one where there is no transition in values between two keyframes. The translation, rotation, or scale value stays remains at what it was at the first keyframe until the 2nd keyframe is reached, then the value shifts abruptly to the new value. <ref>[https://docs.toonboom.com/help/storyboard-pro-6/storyboard/reference/views/function-editor-view.html?Highlight=stop-motion%20keyframe Function Editor View] Storyboard Pro User Guide</ref>

* Apply two keyframes in the '''Timeline'''.
* With the '''Transform''' tool selected (square with 9 control points), '''Tool Properties''' tab > '''Keyframes''' panel > '''Open Function Editor''' button (an S-shaped bezier)
* Make sure the desired transform is selected under '''Functions''', e.g. `Angle_z` if working on a rotation.
* Select the first keyframe in the transform.
