In VIM, how do I break one really long line into multiple lines?

Question

Say I have a super long line in the VIM editor (say around 300+ characters). How would I break that up into multiple lines so that the word boundaries roughly break at 80 chara

Answer 1

To split long lines in the complete document without removing already present line breaks, use:

:set formatoptions+=w
:set tw=80
