+        for more info.
+        
+        The label string for the normal menu items (not separators) may include the 
+        accelerator which can be used to activate the menu item from keyboard.
+        An accelerator key can be specified using the ampersand <tt>&</tt> character. 
+        In order to embed an ampersand character in the menu item text, the ampersand 
+        must be doubled.
+        
+        Optionally you can specify also an accelerator string appending a tab character 
+        <tt>\\t</tt> followed by a valid key combination (e.g. <tt>CTRL+V</tt>).
+        Its general syntax is any combination of @c "CTRL", @c "RAWCTRL",  @c
+        "ALT" and @c "SHIFT" strings (case doesn't matter) separated by either
+        @c '-' or @c '+' characters and followed by the accelerator itself.
+        Notice that @c CTRL corresponds to the "Ctrl" key on most platforms but
+        not under Mac OS where it is mapped to "Cmd" key on Mac keyboard.
+        Usually this is exactly what you want in portable code but if you
+        really need to use the (rarely used for this purpose) "Ctrl" key even
+        under Mac, you may use @c RAWCTRL to prevent this mapping. Under the
+        other platforms @c RAWCTRL is the same as plain @c CTRL.
+
+        The accelerator may be any alphanumeric character, any function key
+        (from F1 to F12) or one of the special characters listed in the table
+        below (again, case doesn't matter):
+        - @c DEL or @c DELETE: Delete key
