Change key in the TMap

This worked for me (using FStrings as keys):

bool RenameItem(FString OldKey, FString NewKey)
{
	if (!Items.Contains(OldKey) || Items.Contains(NewKey))
		return false;

	auto v = Items[OldKey]]; // Store the current value
	Items.Remove(OldKey);    // Get rid of the old key (and it's value)
	Items.Shrink();
	Items.Add(NewKey, v);    // Re-add the stored value using the new key

	return true;
}
