I'm trying to detect how many times a key is pressed. I'm trying to set up an old phone type of keyboard, so if I press 2 once I get "A", if I press 2 twice I get "B" and if I press 2 a third time I get "C".

This is what I have so far, but it's not working properly. The console shows no errors, but if I press 2 twice it alerts A twice instead of B, if i press 2 three times it alerts A three times instead of C.

1. var abcKey = 0;
   
   $(document).on('keyup', function( e ){
   
     if(e.which==50){         // Keyboard number 2   
   
   if(abcKey===2){
   setTimeout(function(){
   alert("C");
   abcKey = 0;
       }, 1000); 
   }
   
   else if(abcKey===1){
       setTimeout(function(){
      alert("B");  
         abcKey = 0;
       }, 1000);
   }
   
   else if(abcKey===0){
       setTimeout(function(){
        alert("A");
         abcKey = 0;
       }, 1000);
   }
   }
   });
   

Hopefully it's something easy to fix, I've working on it for quite a while and can't figure out the problem.
