public class KeyEventsRedirector
extends javax.swing.AbstractAction

Class KeyEventsRedirector redirects keyboard events to a specified component. This class is useful for situations where a given component always wants to process certain keystrokes, regardless of whether or not the component has the current input focus. To intercept keystrokes, accelerators are defined on menu items held in an invisible menu that is added to a displayed menu bar. If a component (such as the target component or a displayed menu) processes a given keystroke then it will not be received by this redirector.
