I added the following settings to my
(add-hook 'org-mode-hook 'turn-on-auto-fill) (add-hook 'org-mode-hook (lambda() (set-fill-column 80)))
When I'm typing sentences in an existing Org-file which are longer than 80 columns, it places on the next line in the Org-file. It works fine.
However, I have in the same Org-file already sentences that I typed in the past, which are longer than 80 columns.
How could I tell Emacs that he must format all sentences in the buffer which are longer than 80 columns. So that the existing words, which exceed 80 columns-limit will begin on the next line?
