Thanks and credit goes out to Xatenev for giving me this script when I asked in lichess.org/forum/general-chess-discussion/anyone-know-javascript-that-could-make-a-very-short-but-extremely-useful-user-script-for-lichess
Here is his answer in full.

I made one for you. It can be found in the following link with syntax highlighting, or just as plain text below:

Press 'p' to go to the previous chapter.
Press 'n' to go to the next chapter.
PS: If you prefer different keys, you can visit keycode.info/ and press the respective key. It will display their "keycode". Replace the numbers 78 and 80 with the keys you want to use. For example, an alternative usage of <left arrow> and <right arrow> would have the keys 37 and 39, so you would replace 80 with 37 and 78 with 39.
