MorseGen is a simple program the purpose of which is to generate Morse Code at whatever speed you feel comfortable reading, for practice purposes. It wasn't designed to be a tutor for those who know no Morse at all, although you might find it useful for that purpose. It doesn't have a feature for sending small character groups over and over, although this can easily be achieved by creating text files containing the character groups you want to practice.
