/**
* @internal
* Handle keyboard accelerators.
*
* Allow an user to configure
* key bindings through application configuration files or through the
* @ref KKeyChooser GUI.
*
* A @ref 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
* @ref 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 @ref insertItem() is used only
* in the configuration dialog.
*<pre>
* 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();
*</pre>
*
* If a shortcut has a menu entry as well, you could insert them like
* this. The example is again the @ref KStdAccel::Print from above.
*
* <pre>
* int id;
* id = popup->insertItem("&Print",this, SLOT(printDoc()));
* a->changeMenuAccel(popup, id, KStdAccel::Print );
* </pre>
*
* 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
*
* <pre>
* id = popup->insertItem(i18n"Scroll &up",this, SLOT(scrollUp()));
* a->changeMenuAccel(popup, id, "Scroll Up" );
* </pre>
*
* Please keep the order right: First insert all functions in the
* acceleratior, then call a -> @ref readSettings() and @em then build your
* menu structure.
*
* @short Configurable key binding support.
