A fairly well-known mapping to toggle boolean options is:
map <F2> :set wrap!<CR>
Nicer, more elaborate versions of this idea exist, such as:
nnoremap <F8> :set wrap! wrap?<CR>
imap <F8> <C-O><F8>
which displays the current value of the option after toggling it, and works both in normal and insert mode.
However, that definition quickly clutters up your vimrc, and is a pain to edit due to the redundant occurrences of the toggle key and option.
Wrapping the definition in a function solves the problem, and makes the toggle definition a one-line operation again:
" Map key to toggle opt
function MapToggle(key, opt)
let cmd = ':set '.a:opt.'! \| set '.a:opt."?\<CR>"
exec 'nnoremap '.a:key.' '.cmd
exec 'inoremap '.a:key." \<C-O>".cmd
endfunction
command -nargs=+ MapToggle call MapToggle(<f-args>)
" Display-altering option toggles
MapToggle <F1> hlsearch
MapToggle <F2> wrap
MapToggle <F3> list
" Behavior-altering option toggles
MapToggle <F10> scrollbind
MapToggle <F11> ignorecase
MapToggle <F12> paste
set pastetoggle=<F12>
