Tutorial by SteelOsprei, explaining journal transitions and all current journal transitions in the Any% route.

Additional info not touched on in the guide:

1. There is a small window on every transition screen where the game drops all inputs. This means if you try to open the journal on one of these very small windows (maybe 1-2 frames), the game will eat your input and the journal won't come out. It hasn't been extensively tested, but I believe the window is right before the journal transition window. This means that if you open the journal too early, you need to flick the journal open and closed in such a way that you avoid the input-eater window, while still hitting the journal transition window immediately after it.

2. During the Dung Journal Transition, if you keep the journal open for ~.75 seconds, two ants should fall on the moving elevator, which will help block the lever from being flipped by any stray dung balls. You can also optionally use one of these ants for Almost Balloonless, if one is able to stay on the platform all the way up.
