Once you are done with the presentation, you can interact with certain UI elements on the pages. Press the 1,2 and 3 keys once done with the presentation to navigate to various pages. On the first page, you can only interact with the arrows on Level 2. This is because anything else on this page would lead to opening websites, which I can't easily replicate in this project but you get the idea. Credits: Massive kudos to the ST for taking user input. There's been controversy in the past over this, and I'm glad that they've found a good way to get input.
