the Space key or Enter key while the element is focused. Note that this
only applies to elements with a default key event handler, and
therefore, excludes other elements that have been made focusable by
setting the
[tabindex](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Global_attributes/tabindex)
attribute.
