The keyboard also has apparatus for comparing a key code in the buffer to a second key code and for generating a modified key code when a match is found, and apparatus for sending the key code to the host computer, the key code sent being the modified key code when the first key code of a word is in the buffer and the key code in the buffer matches the second key code of the word.
