• 1 Why not just perform the action that the CTRL+C key should perform with: document.execCommand("copy") – Scott Marcus Commented Feb 2, 2017 at 17:04
• @ScottMarcus Not copy but ctrl+c. It just the start, there are lots of other plex things there and only ctrl+c would work there as my Team Leader told me. – user7507073 Commented Feb 2, 2017 at 17:06
• @user7507073 CTRL+C is the operating system mand for copy. But, my answer would still be the same. Just call the functions that initiate the "lots of other plex things". The key presses aren't necessary. – Scott Marcus Commented Feb 2, 2017 at 17:08
• @ScottMarcus Alright dear, thank you! But, isn't there any way to do so? Your help will be highly appreciated. – user7507073 Commented Feb 2, 2017 at 17:11

Working fiddle.

Since you're using jQuery you could do it using jQuery.Event :

var e = jQuery.Event("keydown");

e.which = 67; // 'C' key code value
e.ctrlKey = true;

$("body").trigger(e);

Hope this helps.

jQuery Solution

$(function(){ //Ready function
  
  //Event that catch the Ctrl+C press (Just for test)
  $("body").keydown(function(e) {
    var code = (e.keyCode ? e.keyCode : e.which);

    if (code == 67) {
      if (e.ctrlKey) {
        alert("Ctrl+C was pressed!!");
      }
    }
  });

  //Event that trigger the 'Ctrl+C' 
  var e = jQuery.Event("keydown");
  
  e.which = 67; // 'C' key code value
  e.ctrlKey = true;
  
  $("body").trigger(e);
})

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Javascript Solution

document.addEventListener('keydown', function (e) {
  if (event.altKey && event.key === 'n') 
  {
    document.querySelectorAll('._180aQody._254QuS8h')[0].click();
  }
});

document.querySelector('._180aQody._254QuS8h').addEventListener('click', function (e) {
  alert("Alt+n was pressed!!");
});

var ev = new KeyboardEvent('keydown', {bubbles: true,  altKey: true,  key: "n"});
document.querySelectorAll('._180aQody._254QuS8h')[0].dispatchEvent(ev);

<button class='_180aQody _254QuS8h'>CLick me using Alt+n</button>
