I don't follow master so I'm not quite sure what's
implemented, but my original suggestion for this was:
(define-key outline-minor-mode-map (kbd "C-<tab>") 'outline-cycle)
(define-key outline-minor-mode-map (kbd "S-<tab>") 'outline-global-cycle)
It's definitely very useful in outline-minor-mode. I use
this for code folding in prog-modes amongst other things and
that's one of the reasons I used C-TAB for outline-cycle
(since TAB often has other uses in prog-modes).
AFAIR people commented that C-TAB wasn't always available in
some terminals and said it should just be on TAB. Fine.
Either way S-TAB should work.
I'd argue that if you're enabling outline-minor-mode in a
major mode that has a binding for TAB, you want it to be
overridden. If not, don't enable the minor mode or change
one keymap to not conflict. Maybe outline-minor-mode should
support a variable option a major mode could set to change
the TAB keybinding or at least not override it with a
minor-mode binding?
