YUI:Keypress Behavior

Adds a keypress event to the current behavior or callback.

Example

$proto('document', {
  Keypress: {
     key: 'escape',
     onKeypress: {
        Fade: {
           opacity: {to: 0}
        }
     }
  }
});

When the user presses the 'Escape' key when the selected element(s) has focus, fire the onKeypress event.
