I think that this is an Emacs not org-mode problem, but maybe somebody
can throw some light on it.
On my computer running 24.5.1 M<up> works as expected. However, on
emacs 25.1.50.1 I get:
Debugger entered--Lisp error: (error "There is no other window")
scroll-other-window(-)
scroll-other-window-down(nil)
funcall-interactively(scroll-other-window-down nil)
call-interactively(scroll-other-window-down nil nil)
command-execute(scroll-other-window-down)
However, in my org buffer:
c-h w org-metaup
org-metaup is on <M-up>
which seems to indicate that the key is correctly bound.
If I start emacs with a minimal config that just has (require
org-mode), I still get the error.
I then tried the "If it doesn't work hit it with the biggest hammer
available" approach:
(require 'org)
(require 'ob-tangle)
(eval-after-load "org"
'(progn
(define-key org-mode-map (kbd "M-<down>") 'org-metadown)
(define-key org-mode-map (kbd "M-<up>") 'org-metaup)))
but emacs thinks that M-<up> is bound to scroll other window.

Best wishes,
Ian.

This probably won't be much help, but occasionally I've noticed unusual
problems with keybindings in Emacs where a key seems to be bound to more
than one command. You might try checking "C-h k <M-up>" and see what it
says.
Also, try with "emacs -q" and "emacs -Q" and see if you can reproduce it
that way. That might help narrow it down.

Hi Ian,

First of all, it is important to know in which major mode you are trying to
use the M-<up>/<down> bindings. They are undefined by defined and are
defined in org-mode-map.
It is also important to know in which minor/major mode maps you are binding
those in your config. I would guess that the problem you see does not occur
in an emacs -Q session?
It's also important to know that a key can be bound to different command in
different minor/major mode maps and in global maps.
Here's the priority:
1. Minor mode map (last enabled minor mode)
2. Major mode map (e.g. org-mode-map)
3. Global map
So even if M-<up> is bound to org-metaup in org-mode-map, if foo-mode-map
(some minor mode map) as that key bound to a function 'bar' and if foo-mode
is enabled in an org-mode buffer, M-<up> will now call 'bar' instead of
'org-metaup'. So it is important to understand the consequences when making
new bindings to minor mode maps (or understand the maps of the minor modes
you enable).

Emacs does not bind M-<up> by default to anything. So my guess is that
somewhere in your config, you are binding that key to scroll other window.
(I myself have been guilty of stepping over org-mode-map bindings in the
past. Now I have learnt when to bind keys in global-map vs my own minor
mode map which I use when I want my bindings to override everything else).
