Abort

When the game hangs on a GUI screen, a standard button or the Escape key may stop responding and leave the client soft-locked. Abort listens for Alt and Backspace at the hardware-input level, below the GUI input listeners, so the hotkey still works in that state and the player can recover without force-killing the Java process.

Abort is built to stay out of the way. It uses a mixin into the low-level GLFW render loop and polls hardware directly, so it adds no measurable overhead when nothing is frozen. Its three actions are Screen Reset, which clears active GUI layers, Safe Disconnect, which closes world handles stuck in a saving state, and Main Menu Exit, which forces a clean render of the title screen.

The mod is client-side only, so it works in singleplayer worlds and on multiplayer servers without any server-side installation. It is published for Fabric only, with Fabric Loader 0.15.0 as the minimum loader version, and the 1.0.0 build targets 1.21.11. The code is open source under the MIT License.
