+ * 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.
+ *
+ * Accelerator is uniquely defined by:
+ *
+ * <itemizedlist>
+ *   <listitem><para>accelerator path</para></listitem>
+ *   <listitem><para>accelerator key</para></listitem>
+ *   <listitem><para>accelerator modifiers</para></listitem>
+ * </itemizedlist>
+ *
+ * The accelerator path must consist of
+ * "&lt;WINDOWTYPE&gt;/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:
+ * "&lt;Gimp-Toolbox&gt;/File/Dialogs/Tool Options...".
+ *
+ * All accelerators are stored inside one global #GtkAccelMap that can be
+ * obtained using gtk_accel_map_get(). See <link
+ * linkend="monitoring-changes">Monitoring changes</link> for additional
+ * details.

+ * In order to avoid having some accelerators changed, they can be locked using
