137 * Registers a new accelerator with the global accelerator map.
138 * This function should only be called once per @accel_path
139 * with the canonical @accel_key and @accel_mods for this path.
140 * To change the accelerator during runtime programatically, use
141 * gtk_accel_map_change_entry().
142 * The accelerator path must consist of "<WINDOWTYPE>/Category1/Category2/.../Action",
143 * where <WINDOWTYPE> should be a unique application-specific identifier, that
144 * corresponds to the kind of window the accelerator is being used in, e.g. "Gimp-Image",
145 * "Abiword-Document" or "Gnumeric-Settings".
146 * The Category1/.../Action portion is most appropriately chosen by the action the
147 * accelerator triggers, i.e. for accelerators on menu items, choose the item's menu path,
148 * e.g. "File/Save As", "Image/View/Zoom" or "Edit/Select All".
