Thanks for the response. Yes, that is obvious. However, I'm trying to turn that on/off quickly only while driving. Any further thoughts?

First, thanks for reading and the help. I use AutoResponder to send an automatic reply when I'm driving to let the person sending the text that I'm not going to read their message until I stop. I also suggest that they call me if it is urgent. I spend 3-4 hours a day in the car and I'm dead...
