I am very interested in using the CW interface, but before either
building the circuit or buying the cable, I wanted to make sure the
software did what I hope. Perhaps I missed the full description, but
in the help screens for CW setup, I only see mention of using F-x keys
to send preset strings. I figure there has to be some way to send
arbitrary text once in the middle of a QSO, but I'm not 100% sure and
would want to be able to do that. Does this feature exist, and how
does one use it?
