/**
 * A KeyStroke represents a key action on the keyboard, or equivalent input
 * device. KeyStrokes can correspond to only a press or release of a particular
 * key, just as KEY_PRESSED and KEY_RELEASED KeyEvents do; alternately, they
 * can correspond to typing a specific Java character, just as KEY_TYPED
 * KeyEvents do. In all cases, KeyStrokes can specify modifiers (alt, shift,
 * control, meta, altGraph, or a combination thereof) which must be present during the
 * action for an exact match.
 * <p>
 * KeyStrokes are used to define high-level (semantic) action events. Instead
 * of trapping every keystroke and throwing away the ones you are not
 * interested in, those keystrokes you care about automatically initiate
 * actions on the Components with which they are registered.
 * <p>
 * KeyStrokes are immutable, and are intended to be unique. Client code cannot
 * create a KeyStroke; a variant of <code>getKeyStroke</code> must be used
 * instead. These factory methods allow the KeyStroke implementation to cache
 * and share instances efficiently.
 * <p>
 * <strong>Warning:</strong>
 * Serialized objects of this class will not be compatible with
 * future Swing releases. The current serialization support is
 * appropriate for short term storage or RMI between applications running
 * the same version of Swing.  As of 1.4, support for long term storage
 * of all JavaBeans&trade;
 * has been added to the <code>java.beans</code> package.
 * Please see {@link java.beans.XMLEncoder}.
