Answer 2

Add an event listener on the document for keydown and listen to the keyCode or value of the key pressed to determine if the key represents an action or not. example:

window.addEventListener(
"keydown",
(event) => {
if (event.defaultPrevented) {
return; // Do nothing if the event was already processed
}

switch (event.key) {
case "ArrowDown":
// Do something for "down arrow" key press.
break;
case "ArrowUp":
// Do something for "up arrow" key press.
break;
case "ArrowLeft":
// Do something for "left arrow" key press.
break;
case "ArrowRight":
// Do something for "right arrow" key press.
break;
case "Enter":
// Do something for "enter" or "return" key press.
break;
case " ":
// Do something for "space" key press.
break;
case "Escape":
// Do something for "esc" key press.
break;
}
})

Answer 4

Paxton Programer the code is written above, to check the key code for each key, you should replace the switch function with either a console.log or alert function to see the keyCode after the event is triggered:

console.log(event.key + " has keyCode: "+event.keyCode)
