I don't see pro-signs in the training program (AR, KN, AS, etc.) I'm using LCWO to teach a code class. Guess I can just send them myself in LCWO lesson format, but it would be nice to include them in the program.
when you use "Convert text to CW" you can produce every prosign by enclosing the two characters like KA within uppercase , and uppercase . on a qwerty keyboard (lower than and greater than keys).
