I am attending SFSU and doing my best to retain all I can about UNIX and vi editor. Needless to say, overwhelming, is an understatement! Fortunately, this little book is a life saver!! Hand-outs that are given usually get "filed" in the book bag or reused at note paper. With this book I instantly became the most popular guy in the class!! I know one day I'll use all these hints, maybe, but for now this pint-sized book has has given me extra confidence in vi editing.
