The condition InventoryMove.INSTANCE.isDisabled() || InventoryMove.hasInputOrNull(currentScreen) is duplicated in KeyboardMixin. Consider extracting this logic into a utility method to reduce code duplication.

Suggested change
if (InventoryMove.INSTANCE.isDisabled() || InventoryMove.hasInputOrNull(currentScreen)) {
if (shouldUnpressAll(currentScreen)) {

Using forEach with a lambda on every screen transition could be inefficient. Consider using a traditional for-each loop or caching the filtered keybindings for better performance.

Suggested change
KeyBinding.KEYS_BY_ID.values().forEach(bind -> {
if (!InventoryMove.isKeyMovementRelated(bind.boundKey.getCode())) {
bind.reset();
}
});
for (KeyBindingbind : KeyBinding.KEYS_BY_ID.values()) {
if (!InventoryMove.isKeyMovementRelated(bind.boundKey.getCode())) {
bind.reset();
}
}
