Fullbright F9

Full Description:

Fullbright gives you an instant keybind to light up the entire world — no more fumbling for torches in dark caves or squinting through nights and the Nether.

Press F9 to toggle fullbright on and off. When it’s on, everything is fully lit, letting you spot ores, mobs, and terrain clearly no matter how dark the area actually is. Press it again to instantly return to normal lighting.

Features:

One-key toggle, no menus or commands needed
Fully client-side — safe for singleplayer, works on any server that allows client-side visual mods
Rebindable keybind (Options → Controls → Fullbright)
Lightweight, does nothing else — just brightness control

Perfect for exploring caves, building at night, or navigating the Nether without constantly placing light sources.

How to Use (in points, if the form has a separate field for it):

Press F9 to turn fullbright on — the world instantly lights up
Press F9 again to turn it off and return to normal lighting
A small on-screen message confirms when it’s toggled on/off
Rebind the key anytime in Options → Controls → Fullbright category
