I use these two mappings, Alt+Enter and Shift+Enter. I've found that
different Vim UIs have issues with one or the other of these, so I map
both.

inoremap <silent> <A-CR> <C-o>:let b:fo=&fo<Bar>set fo-=r<CR><CR>x<Backspace><C-o>:let &fo=b:fo<Bar>normal! gi<CR>
inoremap <silent> <S-CR> <C-o>:let b:fo=&fo<Bar>set fo-=r<CR><CR>x<Backspace><C-o>:let &fo=b:fo<Bar>normal gi<CR>

I believe Raimondi on FreeNode did most of the work on creating these.
fo is formatoptions (:h formatoptions).
