Smart Shift
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Smart Shift lets you quickly collect smelted items from furnaces by simply holding Shift.
You can also transfer items directly from your hand into containers while holding Shift.
Hold Shift and right-click with seeds to automatically plant crops in a 3x3 area.
