Ctrl-TAB does not seem to work in menu

[Gabor Szabo]

I have the following two menu entries:

    EVT_MENU(
        $self,
        $menu->{view}->Append(-1, "Next File A\tCtrl-TAB"),
        \&on_next_pane,
    );

    EVT_MENU(
        $self,
        $menu->{view}->Append(-1, "Next File B\tCtrl-R"),
        \&on_next_pane,
    );

the only difference is the hot-key.
the Ctrl-R work the Ctrl-TAB does not work even though it is advertised
that it should in  http://docs.wxwidgets.org/2.6.3/wx_wxmenu.html#wxmenuappend

Am I doing something wrong or is there a bug somewhere else?
