The quick brown fox jumps over the lazy dog

Hi there. I do agree with you when you say that this is such a helpful statement particularly as a practice exercise for typing. I still remember when I was still a freshman in my college years about a decade ago; our teacher in Typing subject would teach us the basics of Typing, like the parts of the typewriter and the places of our fingers in the machine. However, after this, we were given practice sets, at least a couple of them, everytime we meet. And while waiting for us to finish our typing tasks, our professor would sit there in front of the whole class and read her pocketbooks or paperbacks. She wouldn't mind if we cheated on ourselves while typing as long as we finished the practice sets within the designated time. When I noticed this, I told myself that I wanted to learn to type without looking at the keys so even if our teacher would care less if we were learning how to type correctly, I made it a point to enhance my typing skills through more practice at home. During this process, this statement which you mentioned here, greatly helped me achieve my short-term objective. But just like you, I find the maker / inventor of this statement "brilliant" for being able to create a sentence where all the basic letters of the alphabet are present. Regards.
