there is simple jquery code below. by this code you can alert or trigger any event on a keyboard key. Must add jquery script.
<script src="https://code.jquery.com/jquery-3.4.1.min.js" integrity="sha256-CSXorXvZcTkaix6Yvo6HppcZGetbYMGWSFlBw8HfCJo=" crossorigin="anonymous"></script>
<script>
$(function () {
$(document).on('keyup keydown keypress', function (event) {
if (event.keyCode == 39) {
alert("right arrow is pressed");
}
else if (event.keyCode == 37) {
alert("left arrow is pressed");
}
else if (event.keyCode == 38) {
alert("up arrow is pressed");
}
else if (event.keyCode ==40) {
alert("down arrow is pressed");
