This worked perfectly Jürgen:

    case '\t':
        if (active_menu == 0) { 
            set_menu_fore(m0, A_NORMAL);
            pos_menu_cursor(m1);
            active_menu = 1;
        } else {
            set_menu_fore(m0, A_STANDOUT);
            active = 0;
                }

You'll notice that I do not turn off the menu cursor for the second menu
because it is acting as a make-shift table(see screen below) and felt
only the command menu on the left should have it's menu deavtivated(My
alternative until now was to save the selected menu item and change the
menu cursor position to an non-O_SELECTABLE menu header(position 0). Then
I would switch it back. Pretty ugly).

  MENU 0                    MENU 1

 Command          Path               Name   <---- non-O_SELECTABLE
 Edit             <home directories> homes
-Add              /tmp               tmp
 Delete           /scratch           public
                 -/share1++++++++++++yo++++ <---- '+' means highlighted

The hash '-' mark on the inactive menu is a nice touch. Also your mention
of pos_menu_cursor solved another little detail. When moving from one
menu to the other the pysical cursor would be left on the inavtive
menu. Calling pos_menu_cursor on the now active menu clears up that
little visual impurity. All in all I'd say this works quite well but
there is still one little problem; the foreground color is initially
white. However after calling set_menu_fore with A_STANDOUT the foreground
color becomes blue. I suspect I should be setting the color attributes
during initialisation?

Thanks,
Mike
