How can I get the "hooked" form of lowercase tau (see below) to show in posts in SE (Math, Theoretical CS, etc.)?

P.S. I tried the "obvious" \vartau, but no dice.

• Have you seen it in any post? If so, which one? How about you edit the post and see what they used? There are options like \uptau and \tauup, both of which require additional fonts/packages which MathJax don't support natively. – Werner Jan 6 '12 at 6:08

You're so close. Try loading the upgreek package and then typing \uptau.
