Similar key bindings for moving among tags in sgml and nxml modes?

Similar key bindings for moving among tags in sgml and nxml modes?

[Lennart Borgman]

I have these routines for moving between tags. I saw now that there
are rather similar sgm functions. Could we please add the same key
bindings to nxml-mode that are used in sgml modes for these?

The first two corresponds to sgml-skip-element-forward/backward.

I do not know the corresponding functions for the last two.


;;; Convenient moving by tags:
(eval-after-load 'nxml-mode
  '(progn
     (define-key nxml-mode-map [C-M-left]  'nxml-backward-element)
     (define-key nxml-mode-map [C-M-right] 'nxml-forward-element)
     (define-key nxml-mode-map [C-M-up]    'nxml-backward-up-element)
     (define-key nxml-mode-map [C-M-down]  'nxml-down-element)))

No, adding different key bindings is the wrong way.  The right way is to
make emacs sexp-movement commands (which are even already bound globally
to the keys you suggest) work properly in nxml-mode .

... and in fact, that's already supported!

Just do:  (setq nxml-sexp-element-flag t)

[I think that should even be the default, but what do I know...]

Thanks. I forgot that flag. I agree it should be on by default.


I think you are right that using the sexp movement is the best. But
what about html-mode/sgml-mode then? Is there also some flag to set to
get this behaviour?

In addition, I would vote for paredit keybindings, too.
