Stops you from dropping items by accident while playing. The drop key does nothing in game, but still works normally in your inventory and chests. Client-side, with a simple settings menu (F9).
Press F9 to open the settings menu, even from the main menu. Enable or disable the mod, and click the second button to switch between blocking only the drop key (A here) or also Ctrl + A.

The menu key (F9 by default) is listed in Options > Controls > Key Binds, in its own "No Drop Hotbar" category, so you can change it to any key you like.
