Hey! I don't know if this is the right term for what I'm describing, but I noticed in weils' world record run there are a few parts where the start/pause menu is used to interact with two elements at once. What I'm talking about is shown:

4:12 - during snowboarding minigame, start is pressed at each action during the first jump and exited after each action is completed 5:03 - at the end of the minigame, the start button is pressed to exit 5:55 - start is pressed to interact with the environment while summoning Bouncer 9:08 - start is pressed to give Flare the letter without triggering cutscene/dialogue 13:36 - start is used to move left while summoning Bouncer 25:59 - start is used to move left while summoning Blast

Would someone be able to explain how this works, or how to do it? Certainly not something I'd come up with myself and I'm quite perplexed lmao. Many thanks!
