+/**
+ * @internal
+ * Handle keyboard accelerators.
+ *
+ * Allow an user to configure
+ * key bindings through application configuration files or through the
+ * KKeyChooser GUI.
+ *
+ * A KAccel contains a list of accelerator items. Each accelerator item
+ * consists of an action name and a keyboard code combined with modifiers
+ * (Shift, Ctrl and Alt.)
+ *
+ * For example, "Ctrl+P" could be a shortcut for printing a document. The key
+ * codes are listed in ckey.h. "Print" could be the action name for printing.
+ * The action name identifies the key binding in configuration files and the
+ * KKeyChooser GUI.
+ *
+ * When pressed, an accelerator key calls the slot to which it has been
+ * connected. Accelerator items can be connected so that a key will activate
+ * two different slots.
+ *
+ * A KAccel object handles key events sent to its parent widget and to all
+ * children of this parent widget.
+ *
+ * Key binding reconfiguration during run time can be prevented by specifying
+ * that an accelerator item is not configurable when it is inserted. A special
+ * group of non-configurable key bindings are known as the
+ * standard accelerators.
+ *
+ * The standard accelerators appear repeatedly in applications for
+ * standard document actions such as printing and saving. Convenience methods are
+ * available to insert and connect these accelerators which are configurable on
+ * a desktop-wide basis.
+ *
+ * It is possible for a user to choose to have no key associated with
+ * an action.
+ *
+ * The translated first argument for insertItem() is used only
+ * in the configuration dialog.
+ *\code
+ * KAccel *a = new KAccel( myWindow );
+ * // Insert an action "Scroll Up" which is associated with the "Up" key:
+ * a->insertItem( i18n("Scroll Up"), "Scroll Up", "Up" );
+ * // Insert an action "Scroll Down" which is not associated with any key:
+ * a->insertItem( i18n("Scroll Down"), "Scroll Down", 0);
+ * a->connectItem( "Scroll up", myWindow, SLOT( scrollUp() ) );
+ * // a->insertStdItem( KStdAccel::Print ); //not necessary, since it
+ *	// is done automatially with the
+ *	// connect below!
+ * a->connectItem(KStdAccel::Print, myWindow, SLOT( printDoc() ) );
+ *
+ * a->readSettings();
+ *\endcode
+ *
+ * If a shortcut has a menu entry as well, you could insert them like
+ * this. The example is again the KStdAccel::Print from above.
+ *
+ * \code
+ * int id;
+ * id = popup->insertItem("&Print",this, SLOT(printDoc()));
+ * a->changeMenuAccel(popup, id, KStdAccel::Print );
+ * \endcode
+ *
+ * If you want a somewhat "exotic" name for your standard print action, like
+ *   id = popup->insertItem(i18n("Print &Document"),this, SLOT(printDoc()));
+ * it might be a good idea to insert the standard action before as
+ *          a->insertStdItem( KStdAccel::Print, i18n("Print Document") )
+ * as well, so that the user can easily find the corresponding function.
+ *
+ * This technique works for other actions as well.  Your "scroll up" function
+ * in a menu could be done with
+ *
+ * \code
+ *    id = popup->insertItem(i18n"Scroll &up",this, SLOT(scrollUp()));
+ *    a->changeMenuAccel(popup, id, "Scroll Up" );
+ * \endcode
+ *
+ * Please keep the order right:  First insert all functions in the
+ * acceleratior, then call a -> readSettings() and @em then build your
+ * menu structure.
+ *
+ * @short Configurable key binding support.
