Answer 1

event.key === "Enter"

More recent and much cleaner: use event.key. No more arbitrary number codes!

NOTE: The old properties (.keyCode and .which) are Deprecated.

const node = document.getElementsByClassName("mySelect")[0];
node.addEventListener("keydown", function(event) {
    if (event.key === "Enter") {
        event.preventDefault();
        // Do more work
    }
});

Modern style, with lambda and destructuring

node.addEventListener("keydown", ({key}) => {
    if (key === "Enter") // Handle press
})
