Visual Studio: Tab key selects and highlights code : <p>If I place my cursor inside a multi-line comment:</p>

<pre><code>/*
 * place cursor after the asterisk and before the word 'place'
 */
if (x == 0) 
{
    // some code
}
</code></pre>

<p>... and hit <kbd>tab</kbd>, Visual Studio doesn't add whitespace as usual.  Instead, it highlights the entire comment (all three lines, in the example).  If I hit <kbd>tab</kbd> again, it will select and highlight the next statement or block of statements.  In my example, it highlights the entire <code>if</code>.</p>

<p>How do I fix this and make Visual Studio tab things over?  I want <kbd>tab</kbd> to behave like a <kbd>tab</kbd>.</p>

<p>I'm using Visual Studio 2013 Ultimate with Resharper 9.  It started doing this yesterday, and I have no idea why.</p>
