Button count different scene - going back [SOLVED]

[hk_jh]

Hi,
I have an arduino code that is part of a music piece. the code have a button that on press it count and go to different "scene"
so when I press first time button count is 1 and therefore scene 1 is playing.
after 10 minute or so I'm pressing again the button. Button count is now 2 and therefore scene 2 is playing. after some more time I'm pressing the button again, therefore button count is 3 and scene 3 is playing.

could happen that because of an exitment of the moment I'm pressing the button twice and now the count is 1 step ahead from what it should be. I would like to have the option that a long press of lets say 3 seconds will count one step back so I will have the option to go back if made a mistake.
How can I do so ?

EDIT:
I found a Solution thank to this post by LarryD

void buttonPress ()
{
    byte currentButtonState = digitalRead (switchPin);
    if (lastButtonState != currentButtonState)  {
        lastButtonState = currentButtonState;

        //******************
        //has the switch been pushed ?
        if (currentButtonState == PUSHED)
        {
           //record the time the switch closed
           timePushed = millis();
          
        }
        //******************
    //switch has been released
    else
    {
      //calculate the time the switch was closed
      timePushed = millis() - timePushed;
      
      if(timePushed < 1800)
      {
        buttonPressCount++;
        millisTimePress = currentMillis;
        Serial.print("buttonPressCount: ");
        Serial.println(buttonPressCount);
        Serial.print("TimePress: ");
        Serial.println(millisTimePress);
        digitalWrite (ledPin, ! digitalRead (ledPin));
      }
      
      else if (timePushed > 2000)
      {
        buttonPressCount--;
        Serial.print("buttonPressCount: ");
        Serial.println(buttonPressCount);
        Serial.print("TimePress: ");
        Serial.println(millisTimePress);
        digitalWrite (ledPin, ! digitalRead (ledPin));
      }
      
    }
  }
}
