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

First set your vim so that it understands that you want 80 characters:

:set tw=80

then, hilight the line:

V

and make vim reformat it:

gq
