In 1.7 modded Minecraft I could have sworn it used to be that:
- Left click an item stack to pick it up
- Hold sneak/shift
- Left click in another inventory, e.g. a chest
This action used to move all of that item into the destination inventory.
Now I'm on 1.12, and it isn't happening.
I have no idea whether it was a Minecraft vanilla thing, or whether it was Inventory Tweaks or Mouse Tweaks doing it, but I still have both of those on 1.12 and it isn't doing it anymore. :/
Does anyone know what used to do it?
