Most of the time I want to have line wrapping on. But, there are some times that I want to toggle it off, to check structures or something... here's a function key for toggling line wrapping:

:set wrap
:let g:toggleWrap = 0
map <silent> <F6> :if g:toggleWrap == 1<CR>:set wrap<CR>:let g:toggleWrap = 0<CR>:else<CR>:set nowrap<CR>:let g:toggleWrap = 1<CR>:endif<CR>

Tom.

" Map F6 to toggle wrap on and off
imap <silent> <F6> <Esc>:set wrap!<CR>a
nmap <silent> <F6> :set wrap!<CR>

Please don't use <esc> ... <a> for insert mode mappings. If you are at the begin of line, it moves the cursor (right). Use Ctrl-O instead:

imap <f6> <c-o>:set wrap!<cr>

and even better:

imap <f6> <c-o><f6>

once <f6> in nmaped as before.

What about:
map <F6> :set wrap!<CR>
?
