"increase quote level" in mail? What does it mean? Only on my mac
I'm not interested in other devices, but on my Mac and MacBook Pro, using the Apple Mail App, using Sierra 10.12.2, what does "increase quote level" mean? I thank you.
And by the way, the behavior of the new TV App on my AppleTV's is super annoying. Any way to get rid of it? Or at least get it to stop interrupting? I thank you.
