Tool Belt 1.20+ [Forge]

Tool Belt is a great visual and practical mod that will help you swap between your items rapidly by giving you a toolbelt you can craft; if you’re not content with its capacity, you can continually expand it by mixing it with a pouch on the anvil, you can add up to 9 slots which is more than enough for any player.

How to install it?

Open the Minecraft launcher and select the version corresponding to your downloaded mod.

Click on the "Mods" button at the top of the launcher window.

Click on the "Open Mods Folder" button. This will open the mods folder where you can install the mod.

Drag and drop the mod file you downloaded into the mods folder.

Close the mods folder and click the "Play" button to launch Minecraft with the mod installed.

That's it! You should now be able to use the mod in Minecraft. If you encounter any issues or errors, try updating Minecraft Forge to the latest version or checking the mod's documentation for troubleshooting tips.
