 /*
 `iron-a11y-keys` provides a normalized interface for processing keyboard commands that pertain to [WAI-ARIA best
 practices](http://www.w3.org/TR/wai-aria-practices/#kbd_general_binding). The element takes care of browser differences
 with respect to Keyboard events and uses an expressive syntax to filter key presses.
 
 Use the `keys` attribute to express what combination of keys will trigger the event to fire.
 
 Use the `target` attribute to set up event handlers on a specific node.
