Legacy Rebindable Keys
by Teknicallity
Legacy Rebindable Keys lets players change the five built-in keys that Minecraft 1.6.4 hardcodes, so they can be moved off the function keys.
What it does
In Minecraft 1.6.4 a handful of function keys are fixed in the game code: F1 hides the interface, F2 takes a screenshot, F3 opens the debug coordinates screen, F5 cycles the camera perspective and F8 toggles the smooth cinematic camera. None of them appear in the controls menu, so they cannot be changed there. This mod lists those five keys under Controls in the Options screen, next to the normal bindings, where they can be reassigned like any other key.
The mod is client-side only, so only the player's client needs it and servers do not. It is released under the MIT License, and the source code and issue tracker are public. Files are published for Forge only, for the 1.6.4 game version, with 1.0 as the latest file from 2026-08-01.
Key features
Rebindable built-in keys
The five hardcoded keys are added to the Controls list, so each one can be given a different key.
Hidden interface toggle
The key that hides the HUD in vanilla can be moved to any key, including a mouse button.
Screenshot and debug keys
The screenshot key and the debug coordinates key can be set to keys that do not conflict with other controls.
Camera and cinematic keys
The camera perspective key and the smooth cinematic camera key can be bound to other inputs.
Compatibility
Latest build for each game version and loader.

Use cases
Freeing function keys
Players who use the function keys for other purposes can move the five built-in actions to free keys.
Mouse bindings
A built-in key can be placed on a mouse button, since the binding accepts mouse input.
Who it’s for: Players on Minecraft 1.6.4 who want to change the default function-key bindings for the built-in actions.

Minecraft 1.6.4 bakes a few of its function keys right into the game code. F5 swings the camera around, F1 hides the interface, F3 pulls up the debug screen. None of them show up in the controls menu, so there is no way to move them off keys you might rather use for something else. This mod changes that. It takes…
