Keyboard button clicks with Space and Enter behave differently

Whenever you add a JavaScript click handler to DOM elements other than the good old button, you should hold on and ask yourself if you're using the correct element. Semantic HTML provides additional functionality to assistive technology and is usually more accessible than clickable div soup.

For example, buttons come with keyboard accessibility features built-in. They're focusable and can be clicked by pressing Enter or Space.

But did you know that the two keys click buttons differently?

• Enter clicks a focused button on keydown
• Space clicks a focused button on keyup

I found this little fun fact on Adrian's blog. Check out the post to learn more and see this click behavior in action.
