<h2>Disable all automatic highlighting, globally, across all tags.</h2>

<p>You won't see a lot of highlighting at all, since it needs to be manually specified by the author (it's explained in <a href="http://serverfault.com/editing-help#syntax-highlighting">editing help</a>, but to really do it right takes a <a href="http://meta.stackexchange.com/a/81970/167585">dig in m.SO</a>) - but at least there won't be any highlighting of something that isn't code.</p>
