Description
# 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 NeoForge and Fabric** (and Forge for older versions) - 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.

Relevant items can also be quickly transferred from your inventory by clicking on them in the query window:

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