I'm also very much in favor of this. I think probably every user has
his own incarnation of such a command.

Well, I think those shouldn't be commands in outline-minor-mode-map as
they should only be active when point is on an outline heading, no? At
least that's the case with org-mode where TAB acts quite differently
depending on the context.
So that's my personal incarnation:
--8<---------------cut here---------------start------------->8---
(defmacro th/define-context-key (keymap key dispatch)
"Define KEY in KEYMAP to execute according to DISPATCH.
DISPATCH is a form that is evaluated and should return the
command to be executed.
If DISPATCH returns nil, then the command normally bound to KEY
will be executed.
Example:
(th/define-context-key hs-minor-mode-map
(kbd \"<C-tab>\")
(cond
((not (hs-already-hidden-p))
'hs-hide-block)
((hs-already-hidden-p)
'hs-show-block)))
This will make <C-tab> show a hidden block. If the block is
shown, then it'll be hidden."
(declare (indent 2))
`(define-key ,keymap ,key
`(menu-item "context-key" ignore
:filter ,(lambda (&optional ignored)
,dispatch))))
(th/define-context-key outline-minor-mode-map (kbd "<tab>")
(when (save-excursion
(move-beginning-of-line 1)
(looking-at-p outline-regexp))
'outline-toggle-children))
--8<---------------cut here---------------end--------------->8---
Of course, outline-toggle-children is not exactly like org-cycle or
org-global-cycle but it gets the job done.
Bye,
Tassilo
PS: On a related note, I think there should be some standard facility
for defining keys depending on the context. If Stefan hadn't shown me
the menu-item-with-:filter trick some years ago, I would probably not
found out myself.
