How to Open the Fullscreen Advancements Window

Opening the Window

The Advancements Fullscreen Mod does not add a new keybind of its own. It changes how the vanilla advancements screen behaves, so you open it exactly the way you always have.

1. Press the advancements key (by default L on Java Edition) while in-game.

2. The window that normally appears as a small panel now fills your entire screen.

3. Press Escape or the same key again to close it and return to the game.

If nothing happens when you press the key, check Options > Controls > Key Binds and confirm the advancements screen is still bound to a key. Another mod may have taken that key for itself.

If the Window Looks Wrong

Because this is a client-side mod, it only affects your own view. Other players on a server still see the normal-sized window, and nothing about your actual advancement progress changes.

If the window opens but is not fullscreen, make sure the mod is actually loaded for the profile you launched. A quick way to check is the mod list on the title screen. If it is listed but the window is still small, another interface mod is likely overriding the same screen, and you will need to disable one of them.
