Detecting Keyboard Click Event

When handling a click event, how do you tell if it’s from keyboard enter key or mouse click? Use a keydown event to set up detection before the click event is called:

var ENTER_KEY = 13;
var isKeyEvent = false;

	.on('keydown', myElem_Key)
	.on('click', myElem_Click)

var myElem_Key = function(e) {
	var key = e.keyCode || e.which;
	if (key == ENTER_KEY) {
		isKeyEvent = true;

var myElem_Click = function(e) {
	if (isKeyEvent) {
		// Handle key event click.
		isKeyEvent = false;

The key event can be tied to multiple elements and the callback used as a pass-through for detection.
