I'm currently using this to toggle line-length -

--8<---------------cut here---------------start------------->8---
(setq-default fill-column 100)
(defvar my-last-fill-col 75 "...")

(defun my-toggle-fill-column ()
   "..."
   (interactive)
   (setq-default my-last-fill-col
                 (prog1 fill-column
                   (setq-default fill-column my-last-fill-col)))
   (message "Fill column is now %d" fill-column))
--8<---------------cut here---------------end--------------->8---

Which works great for individual paragraphs, but now I want to toggle
the line-length of an entire document, but I can't work out how I'm
supposed to do it, so can anyone help please? Great aunt google hasn't
been much help so far! :)

Any ideas please folks?

Thanks
Sharon.

See these commands: `fill-region', `fill-nonuniform-paragraphs', and
`fill-individual-paragraphs'.

   (setq-default ...)

Just curious: Why do you use ‘setq-default’?

Because its worked well for me since 22/04/2015 when I first set it up.

Thanks
