I need to simulate a key press. However I have just been able to find this:

var press = jQuery.Event("keypress");
press.ctrlKey = false;
press.which = 75;
$("whatever").trigger(press);

Where "whatever" is an input field or something. However I don't need to target any element. How can I simulate a key press (the 'k' key to be specific) without targeting any element?

    i guess your target element can be body, document or window (i would go for body, it is here i used to place the keypressed events) – Kaddath Jul 12 '17 at 12:13

if you dont want to target any element, you will have to target the body directly, that way, any key should trigger what you want

$(document).ready(function(){
    $("body").keypress(function(){
        alert('hey');
    });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Targeting the body will give you the sense of targeting nothing.

CharCode()

function showChar(e)
{
alert("Key Pressed: " + String.fromCharCode(e.charCode) + "\n"
      + "charCode: " + e.charCode);
}
<body onkeypress="showChar(event);">

Do it like this: 

$('body').keypress(function(e){
  if ( e.which == 75 ) { 
    alert('hey k was pressed');
  }
});

Have a look at this list of char codes
