I've found that I'd assigned 'C-x o' to two things in my config file,
one of which is to 'outline-minor-mode-prefix', so I commented out the
unused one and restarted emacs.

But it still didn't work, so I searched in my config for
'outline-minor-mode-prefix' and found that I'd assigned it twice, so I
commented out the second instant, and restarted again.

But it still didn't work, so this what I've got it showing as -

--8<---------------cut here---------------start------------->8---
 (global-set-key (kbd "C-x o") 'outline-minor-mode-prefix)
--8<---------------cut here---------------end--------------->8---

If I comment out that line and restart it shows that 'C-x o' is unassigned.

But if I do 'C-x o' now , it shows

--8<---------------cut here---------------start------------->8---
(wrong-type-argument commandp outline-minor-mode-prefix) in command-execute
--8<---------------cut here---------------end--------------->8---

So where do I go from here please?

I don't have windmove or ace-window installed, but I'm quite prepared to
if it means that I get the required functionality.

Thanks
Sharon.
