Iventory Vertical Swap
The author built this one for Minecraft 1.21.1 on NeoForge. On other versions it may install and then do nothing.
This is a simple client-side utility mod. Just hold the hotkey (Default: Left Ctrl) or long-press a number key, then scroll your mouse wheel to seamlessly swap items between your active hotbar slot and the inventory column above it.
