Keyboard Tabbing to Anchors with jQuery

Working on keyboard accessibility the other day, I found out that an anchor will receive focus if you tab to it but will only trigger a jQuery click event if the anchor has an href attribute.

	Doesn't work with return/enter key
</a><br />

<a href="#keyboard-click-event">
	It works!
</a><br />

To trigger a click event using keyboard, tab to the element and press return/enter key.
