This text:

------

@code{local-function-key-map} inherits from @code{function-key-map},
but the latter should not be used directly.

------

was added by this commit:

commit 6b9e769476955b928b0248fef5aaa0e40754e257

    (Translation Keymaps): Rename function-key-map to local-function-key-map.

------


So I'm assuming that there was a plan to phase out using
function-key-map or something?  Perhaps Eli can clarify.

But there's a bunch of examples in the manual that does use the map, so
either these should be adjusted, or the documentation clarified:

------

The only way to affect the behavior of keys within Emacs is through
@code{xmodmap} (outside Emacs) or @code{define-key} (inside Emacs).  The
@code{define-key} command should be used in conjunction with the
@code{function-key-map} map.  For instance,

@lisp
(define-key function-key-map [M-@key{TAB}] [?\M-\t])
@end lisp
