Asking because I need this as an anti-bot answer to register on a different forum. MC is getting marked as incorrect, so there must be some trick that I am missing.

CW is used to refer to it, though improper because CW is actually a modulation method and not type of code. It's fun looking at the other types of codes. My favorite is the Wabun code https://en.m.wikipedia.org/wiki/Wabun_code

Actually there is not a generally accepted TWO letter code for Morse Code.
The best you can do is the three letter FCC emission designator, A1A, which actually specifies that the data is conveyed by the on and off keying of a transmitter.
The FCC emission designator does NOT indicate "Morse Code" specifically.
Also Morse code comes in several flavors, Continental, International, Cyrllic, Kata Kana,(Japanese) etc.
Are you trying to specify which flavor of Morse Code is being used, or are you trying to specify that the data is being conveyed by the on/off keying of a transmitter?

That's just Morse is a specific type of code, the International we use today and the old American/Railway version. The others are just on off keyed code and have nothing to do with Morse.
While on the Subject of CW....
Our radio club recently had the opportunity to attend presentations by newly-minted hams from the local college. They presented some interesting facts:
Samuel Morse was an artist (painter) and studied at NYU where he met Alfred Vail (theology student) who helped developed the code.
Morse's original code scheme was to assign a number for each word, then you looked up the number in a very thick book to get the translation. Vail actually came up with the idea to use dots and dashes.
Some of the early code reader machines consisted of 4 or 5 needles that would point to a character of the alphabet when receiving a transmission.
Neat stuff.

I was surprised no one developed an Morse code “answering machine” to record messages while some one was away.
They did. Some of the devices used chemically treated paper to record the message. It was then read by the telegrapher.
BTW, the code was CW before it was anything else. The only from of keying a signal was on and off. Of course in the days of the land telegraph before radio it was the keying on and off of a direct current.
Then for wireless communication it was the keying on and off of a spark gap transmitter.
To be clear technically, the spark gap transmitter produces a damped wave, the next step using high frequency alternators produced a continuous wave.
In terms of the transmission of information it was till the keying on and off of a continuous wave regardless of the form of the code.

With all this code talk,it make me want to get back in to CW......
