/**
 * Accelerator maps are used to define runtime configurable accelerators.
 * Functions for manipulating them are are usually used by higher level
 * convenience mechanisms like #GtkUIManager and are thus considered
 * “low-level”. You’ll want to use them if you’re manually creating menus that
 * should have user-configurable accelerators.
 * 
 * An accelerator is uniquely defined by:
 * - accelerator path
 * - accelerator key
 * - accelerator modifiers
 * 
 * The accelerator path must consist of
 * “<WINDOWTYPE>/Category1/Category2/.../Action”, where WINDOWTYPE
 * should be a unique application-specific identifier that corresponds
 * to the kind of window the accelerator is being used in, e.g.
 * “Gimp-Image”, “Abiword-Document” or “Gnumeric-Settings”.
 * The “Category1/.../Action” portion is most appropriately chosen by
 * the action the accelerator triggers, i.e. for accelerators on menu
 * items, choose the item’s menu path, e.g. “File/Save As”,
 * “Image/View/Zoom” or “Edit/Select All”. So a full valid accelerator
 * path may look like: “<Gimp-Toolbox>/File/Dialogs/Tool Options...”.
 * 
 * All accelerators are stored inside one global #GtkAccelMap that can
 * be obtained using gtk_accel_map_get(). See
 * [Monitoring changes][monitoring-changes] for additional
 * details.
 * 
 * # Manipulating accelerators
 * 
 * New accelerators can be added using gtk_accel_map_add_entry().
 * To search for specific accelerator, use gtk_accel_map_lookup_entry().
 * Modifications of existing accelerators should be done using
 * gtk_accel_map_change_entry().
 * 
 * In order to avoid having some accelerators changed, they can be
 * locked using gtk_accel_map_lock_path(). Unlocking is done using
 * gtk_accel_map_unlock_path().
 * 
 * # Saving and loading accelerator maps
 * 
 * Accelerator maps can be saved to and loaded from some external
 * resource. For simple saving and loading from file,
 * gtk_accel_map_save() and gtk_accel_map_load() are provided.
 * Saving and loading can also be done by providing file descriptor
 * to gtk_accel_map_save_fd() and gtk_accel_map_load_fd().
 * 
 * # Monitoring changes
 * 
 * #GtkAccelMap object is only useful for monitoring changes of
 * accelerators. By connecting to #GtkAccelMap::changed signal, one
 * can monitor changes of all accelerators. It is also possible to
 * monitor only single accelerator path by using it as a detail of
 * the #GtkAccelMap::changed signal.
