How do I stop the coroutine until one or more of multiple conditions are met?

I need a Coroutine to stop until one of the conditions is met. Particularly, I need coroutine to wait until user presses one of two keys (R or T), or when my "timer" goes off, and then I need coroutine to continue. Timer is a float variable which I decrease by Time.deltaTime in Update method. Basically, I need to put a couple of conditions in yield return new WaitUntil() , if it is possible. I know how to write conditions themselves, but I don't know what to use to stop the coroutine until one of multiple conditions are met.

So is there a way to do something like that?

I think you are over complicating it.. so. This is not a whato todo but a working example of how to use multiple conditions.

I have not compiled this code so typos galor I expect..

bool inputreceived=false;
IEnumerator test()
{
   inputreceived = false;
   yield return new WaitUntil(inputreceived);
   dostuff();
}

void Start()
{
  StartCoroutine("test"); // or use a better non string manner
}

void Update()
{
  if (Input.GetKeyDown(Keycode.R) || Input.GetKeyDown(Keycode.T)) inputreceived=true;
}

You could do

IEnumerator ConditionCoroutine()
{
    print("Before condition");
    
    var hasPressedR = false;
    var hasPressedT = false;
    float timer = XY;
 
    while(true)
    {
        timer -= Time.deltaTime;
        if(Input.GetKeyDown(KeyCode.R)) hasPressedR = true;
        if(Input.GetKeyDown(KeyCode.T)) hasPressedT = true;

        if(timer <= 0 && hasPressedR && hasPressedT)
        {
            break;
        }

        yield return null;
    }
    
    print("After condition");
}

and avoid having a lot of fields in your class itself or depending on Update.

IEnumerator ConditionCoroutine()
{
    print("Before condition");
    
    yield return new WaitUntil(() =>
        (Input.GetKeyDown(KeyCode.R) || Input.GetKeyDown(KeyCode.T) || IsTimerEnd)
    );
    
    print("After condition");
}
