Use Item Within Gui
by Sakurafuld
Use Item Within Gui lets players use the item in hand while a container or interface screen is open, without closing it first.
What it does
Holding an item and pressing Ctrl with the right mouse button outside a GUI uses that item from the main hand. Inside a GUI, the same key combination on a non-slot area performs the standard right-click action, such as opening a container. Shift adds sneaking to the use, and Alt places the used item into the hand, which covers backpack items as well. Even with nothing equipped, a player can interact with blocks this way.
The mod works with Forge and NeoForge for 1.20.1 and 1.21.1, where the latest files are 1201.1.0 and 1211.1.0, both dated 2025-09-27. It is open source under the MIT License, and the source code is public. The environment is client-side only, so a multiplayer server does not need to install it, but the mod is listed as requiring a server-side install when playing on multiplayer. Players on a server that runs it need the client part to use the feature.
