That quick zoom in when editing texts...

Anytime time I put the cursor anywhere, when editing texts, or beginning this very sentence, and boom. Auto zoom. Can that be a option to turn on and off? I always have to back out, in order to re-read my texts. Plus if it zooms in too much, I won't even see the cursor, and will end up with garbled words and mixed up sentences. Thanks! Sorry for so many posts, I love this site already, and it needed to be said.
