Unfortunately, for the scenario I was replying to, a lot of the times when you’re doing support, you can’t see the user’s screen and are limited to verbal communication, so verifying what they typed or the output can lead to just as many problems. Any support scenario where you’re talking the other person through a series of tasks will be very dependent on how familiar each person is with the task you’re supporting. And no one Rs TFM these days, if you even get one.
