In this recipe, we only showed the key code values for the arrows. There is, of

If you want to know the key
value of a specific key, and you don't feel like looking up the value in a list, you can

console:
function setupKeyLogger() {
document.onkeydown = function(e) {
console.log(e);
}
}
This small handler logs the complete event. In the output to the console, you can
then see the key code that is used, as shown in the following screenshot:
