+        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
+        - @c BACK : Backspace key
+        - @c INS or @c INSERT: Insert key
+        - @c ENTER or @c RETURN: Enter key
+        - @c PGUP: PageUp key
+        - @c PGDN: PageDown key
+        - @c LEFT: Left cursor arrow key
+        - @c RIGHT: Right cursor arrow key
+        - @c UP: Up cursor arrow key
+        - @c DOWN: Down cursor arrow key
+        - @c HOME: Home key
+        - @c END: End key
+        - @c SPACE: Space
+        - @c TAB: Tab key
+        - @c ESC or @c ESCAPE: Escape key (Windows only)
+
+        Examples:
+
+        @code
+        m_pMyMenuItem->SetItemLabel("My &item\tCTRL+I");
+        m_pMyMenuItem2->SetItemLabel("Clean && build\tF7");
+        m_pMyMenuItem3->SetItemLabel("Simple item");
+        m_pMyMenuItem4->SetItemLabel("Item with &accelerator");
+        @endcode
+
+        @note In wxGTK using @c "SHIFT" with non-alphabetic characters
+        currently doesn't work, even in combination with other modifiers, due
+        to GTK+ limitation. E.g. @c Shift+Ctrl+A works but @c Shift+Ctrl+1 or
+        @c Shift+/ do not, so avoid using accelerators of this form in portable
+        code.
