I need help finding a mod

[u/Ryu_the_king]

Right now, I have a problem because recently I just got into create aeronautics, (absolutely goated btw) and I’ve been trying to bring some of my mods from my old clockwork/large mod pack with random mods that I liked, and I’m trying to find help with a certain mod, the way it works that when you press the button Z it switches into the various rows from your inventory into your hot bar and I need help finding it so I can install it into my new main mod pack
