" at top of paragraph, format this paragraph
!} fmt -c

" for the whole file, format all paragraphs
!G fmt -c

"from here to the end of the file, format all paragraphs
!$ fmt -c

" from anwhere in the paragraph, format this paragraph
{!}fmt -c


Here's how I map them in my .exrc file:
map @f !} fmt -c^M
map @F !G fmt -c^M
map ^Xf !$ fmt -c^M
map ^XF {!}fmt -c^M}^M

P.S. the -c option to fmt is for "crown" formatting, preserving the
indention of the first 2 lines within a paragraph.  You can leave it
off.
