Safari has a preference that puts those elements in the tab order, and
it allows you to get that effect on the fly by holding the option key

Also, buttons (and links) can be focused at any time with JavaScript
focus() calls.

The spec caters for this.
Can <input type="button"> controls be focused at all, on OS X?
