| 2 ======================= | |
| 3 | |
| 4 `Polymer.IronA11yKeysBehavior` provides a normalized interface for processing | |
| 5 keyboard commands that pertain to [WAI-ARIA best practices](http://www.w3.org/TR
/wai-aria-practices/#kbd_general_binding). | |
| 6 The element takes care of browser differences with respect to Keyboard events | |
| 7 and uses an expressive syntax to filter key presses. | |
| 8 | |
| 9 Use the `keyBindings` prototype property to express what combination of keys | |
| 10 will trigger the event to fire. | |
| 11 | |
| 12 Use the `key-event-target` attribute to set up event handlers on a specific | |
| 13 node. | |
| 14 The `keys-pressed` event will fire when one of the key combinations set with the | |
| 15 `keys` property is pressed. | |
