Thanks to the coronavirus crisis, my 280-odd colleagues on the University of Texas School of Law faculty are valiantly struggling to transpose their years of classroom skill and content to the daunting digital realm of remote instruction using Zoom teleconferencing. Zoom has been a part of the University of Texas’ Canvas learning platform for less than 48 hours, and over 3,000 professors at UT Austin have just two weeks to be ready to teach via Zoom when some 40,000 students return from an extended spring break. That’s just the UT Austin campus. It’s closer to a quarter of a million students and 21,000 faculty in the whole UT system who face this unprecedented test of their resiliency. I’m deeply proud of how hard everyone is trying to rise to the challenge.

I’ve taught classes with Zoom for years, so apart from misplacing a window now and then, I find Zoom simple to use and navigate. In a modest effort to help my colleagues, I prepared a one-page cheat sheet. It might help anyone trying to use Zoom to navigate Law in the Time of Cholera, I mean, Coronavirus. You can download it here, and its text follows:
