Modeline magic

==Adding a modeline==
With the following in your [[vimrc]] and the default leader key, you could type <code>\ml</code> to add a modeline based on your current settings:
<pre>
" Append modeline after last line in buffer.
" Use substitute() instead of printf() to handle '%%s' modeline in LaTeX
" files.
function! AppendModeline()
  let l:modeline = printf(" vim: set ts=%d sw=%d tw=%d %set :",
        \ &tabstop, &shiftwidth, &textwidth, &expandtab ? '' : 'no')
  let l:modeline = substitute(&commentstring, "%s", l:modeline, "")
  call append(line("$"), l:modeline)
endfunction
nnoremap <silent> <Leader>ml :call AppendModeline()<CR>
</pre>

In a C file, you would get a modeline like this:
<pre>
/* vim: set ts=8 sw=4 tw=0 noet : */
</pre>

Alternatively, you could use a simple menu entry, for example:
<pre>
amenu Edit.Insert\ &modeline <C-\><C-N>ggOvim:ff=unix ts=4 ss=4<CR>vim60:fdm=marker<Esc>
</pre>

Choosing the menu item would insert two modelines like this:
<pre>
vim:ff=unix ts=4 ss=4
vim60:fdm=marker
</pre>
