Use the left & right arrow keys or A and D to change slides. Five-step instructions for personal use of the engine are shown in the slide show.
I saw many users use various slide show engines to present information on scratch. I noticed that many of these engines were slow and clunky to use, with long animations and no way to quickly switch between multiple slide. I made Slide Engine to be versatile to use, precise to control, and elegant to view. Thanks to the scratch team for the feature!
