Don’t have a clue
Flossie, well, you have two choices: either get rid of your Mac or type faster 😉 Just kidding of course.
This never happened to me and I am typing darnd slow these days, but I don’t have a Mac. I looked at your profile and it looks normal to me.
Do you actually get a message? What happens to me sometimes is that I lose everything I typed. I assume it is because I hit a strange key combination with my numb fingers. But there never is a message.
