There are also a lot of morse decoder programs which take your receiver
audio output and display it as text. Even if you are getting quite good
at morse, and are pretty good at decoding it 'in your head', the display
of the text 'subtitles' provides an instant indication of how you are
doing. Some programs indicate the speed of the received morse, and I was
surprised that I now seem to be able to copy quite a lot at up to 20wpm.

I don't think there's a radio made that doesn't call it "CW". The VBR
binary system invented by S. F. B. Morse for electric clicker DC wire
communications might resemble CW at first glance, but modern CW is quite
different.
