Query: What "asdf jkl;" really means.

This classic text provides a quick method for learning to type for speed and accuracy. (I recommend it for Grades 6 and up)It is divided into brief step-by-step lessons beginning with the home keys "a s d f j k l ;" and ending with speed and accuracy tests on full text transcriptions.When I was in high school, I used this book to learn how to type during February school vacation. I did a three lessons a day, 30 mins each morning, afternoon, and evening. In one week, I went from 0 to 35-55 words per minute.The result of the easy instructions and simple drill and practice lessons was a skill which has served me well ever since.Highly recommended.
