keydownScoped

Method decorator that will look for changes to its targeted component's
`keydown` props to decide when to trigger, rather than responding directly
to keydown events. This lets you specify a @keydown decorated class higher
up in the view hierarchy for larger scoping of keydown events, or for
programmatically sending keydown events as props into the components in order
to trigger decorated methods with matching keys.

@access public
@param {Array} ...args  All (or no) arguments passed in from decoration
@return {Function} The decorated class or method
