+/**
+ * Handle shortcuts.
+ *
+ * Allow a user to configure shortcuts
+ * through application configuration files or through the
+ * KKeyChooser GUI.
+ *
+ * A KAccel contains a list of accelerator actions.
+ *
+ * For example, CTRL+Key_P could be a shortcut for printing a document. The key
+ * codes are listed in qnamespace.h. "Print" could be the action name for printing.
+ * The action name identifies the shortcut in configuration files and the
+ * KKeyChooser GUI.
+ *
+ * A KAccel object handles key events sent to its parent widget and to all
+ * children of this parent widget. The most recently created KAccel object
+ * has precedence over any KAccel objects created before it.
+ * When a shortcut pressed, KAccel calls the slot to which it has been
+ * connected. If you want to set global accelerators, independent of the window
+ * which has the focus, use KGlobalAccel.
+ *
+ * Reconfiguration of a given shortcut 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. A convenience method is
+ * 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* pAccel = new KAccel( this );
+ *
+ * // Insert an action "Scroll Up" which is associated with the "Up" key:
+ * pAccel->insert( "Scroll Up", i18n("Scroll up"),
+ * i18n("Scroll up the current document by one line."),
+ * Qt::Key_Up, this, SLOT(slotScrollUp()) );
+ * // Insert an standard acclerator action.
+ * pAccel->insert( KStdAccel::Print, this, SLOT(slotPrint()) );
+ *
+ * // Update the shortcuts by read any user-defined settings from the
+ * // application's config file.
+ * pAccel->readSettings();
+ * \endcode
