I want to make a slide show that waits at each frame until the user presses a key.
I've checked and found Prezi, an online service that allows you to create slideshows and presentations where you can control the way the presentation is displayed. There is also the possibility to manually advance to the next frame or go back in case you've missed something.
Use the following website and look at the examples to see how it works: https://prezi.com/
