This feature request was closed, so in a new feature request
in https://debbugs.gnu.org/45147#8 this is implemented as a new variable
'outline-minor-mode-cycle' that you can set to t to allow cycling keys
in 'outline-minor-mode', and a keymap 'outline-mode-cycle-map' where you
can define your bindings such as C-TAB instead of the default key TAB.
