Neither can I.  When I need it, which is rarely, there's C-h m.

But you can't use TAB to indent a line, or alternatively to insert a tab
character.  And how is a non-specialist user reading NEWS for a new
release going to find out about this TAB binding?

There are not "countless" keybindings in outline-mode; there are just 26
defined commands, only some of which will have bindings.  By contrast,
in org-mode there are 798 defined commands.  That's a factor of 30
greater.

That may be true up until somebody decides to insert some obscure
org-mode construct into NEWS.  With over 4 magabytes of source code
implementing it, there will be more than a few such constructs.

Maybe it should be.
