About this project

What does What's That Slot? add?

What's That Slot

This mod is a simple utility that allows you to query which items can be placed in a specific slot by holding down Left-Alt. The mod supports both Forge and Fabric- make sure to select the right file!

This is particularly useful in modded environments where it may not be clear what items can be placed in a modded GUI.

Demonstration

Relevant items can also be quickly transferred from your inventory by clicking on them in the query window: Demonstration of Quick-Move

This mod works client-only, so it does not need to be installed on the server to run!
