Chart of the Morse code 26 letters and 10 numerals [1]. This Morse key was originally used by Gotthard railway, later by a shortwave radio amateur [2]. Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs.
Morse code abbreviations are not the same as prosigns.Morse abbreviations are composed of (normal) textual alpha-numeric character symbols with normal Morse code inter-character spacing; the character symbols in abbreviations, unlike the delineated character groups representing Morse code prosigns, are not "run together" or concatenated in the way most prosigns are formed.
Morse code mnemonics are systems to represent the sound of Morse characters in a way intended to be easy to remember. Since every one of these mnemonics requires a two-step mental translation between sound and character, none of these systems are useful for using manual Morse at practical speeds.

Other names for this function are: Not equal (NEQ), modulo 2 addition (without 'carry') and modulo 2 subtraction (without 'borrow'). Vernam's cipher is a symmetric-key algorithm, i.e. the same key is used both to encipher plaintext to produce the ciphertext and to decipher ciphertext to yield the original plaintext:
In Morse code, it is known as a "commat", consisting of the Morse code for the "A" and "C" which run together as one character: . The symbol was added in 2004 for use with email addresses, [55] the only official change to Morse code since World War I. In Nepali, the symbol is called "at the rate." Commonly, people will give their email ...

Alfred Vail and Samuel Morse collaborated in the invention of Morse code. The "Morse code" that went into operational use after Vail had become involved was very different from Morse's original plan. [c] A controversy exists over the role of each in the invention. The argument for Vail being the original inventor is laid out by several scholars.
