+/**
+ * A KeyEventPostProcessor cooperates with the current KeyboardFocusManager
+ * in the final resolution of all unconsumed KeyEvents. KeyEventPostProcessors
+ * registered with the current KeyboardFocusManager will receive KeyEvents
+ * after the KeyEvents have been dispatched to and handled by their targets.
+ * KeyEvents that would have been otherwise discarded because no Component in
+ * the application currently owns the focus will also be forwarded to
+ * registered KeyEventPostProcessors. This will allow applications to implement
+ * features that require global KeyEvent post-handling, such as menu shortcuts.
+ * <p>
+ * Note that the KeyboardFocusManager itself implements KeyEventPostProcessor.
+ * By default, the current KeyboardFocusManager will be the final
+ * KeyEventPostProcessor in the chain. The current KeyboardFocusManager cannot
+ * be completely deregistered as a KeyEventPostProcessor. However, if a
+ * KeyEventPostProcessor reports that no further post-processing of the
+ * KeyEvent should take place, the AWT will consider the event fully handled
+ * and will take no additional action with regard to the event. (While it is
+ * possible for client code to register the current KeyboardFocusManager as
+ * a KeyEventPostProcessor one or more times, this is usually unnecessary and
+ * not recommended.)

+     * requesting that this KeyEventPostProcessor perform post-processing
+     * of the event again.

+     * If an implementation of this method returns <code>false</code>, then the

+     * further action with regard to the KeyEvent. If an implementation
+     * consumes the KeyEvent but returns <code>false</code>, the consumed
+     * event will still be passed to the next KeyEventPostProcessor in the

+     * been consumed before performing any post-processing of the KeyEvent. By

+     * processing in response to a consumed KeyEvent.
