Keybind Overrides is a tiny client-side utility for modpack creators. It applies a curated set of keybind defaults on the very first launch of the pack—without shipping options.txt and without forcing players to restart. On first load it reads config/keybindoverrides-client.toml, overwrites any listed keybinds (vanilla + modded), saves options.txt, then automatically flips applyOverrides to false so players keep their own tweaks afterward. Supports modifiers (Shift/Ctrl/Alt), unbinding via key.keyboard.unknown, and works alongside any mod that registers keymappings. If you need to reapply on an update, just set applyOverrides = true again.

How to use

Launch once to generate config/keybindoverrides-client.toml.
Set applyOverrides = true and list overrides as key_name:key_value[:MODIFIER] (copy from your options.txt).
Ship the pack; first launch applies and disables itself. No restart needed.

Why use it

Prevents key conflicts across large modpacks.
Doesn’t wipe player settings on updates (unlike bundling options.txt).
Immediate effect; no reboot required.
