 Typewriters in Portuguese-speaking countries generally have a separate extra key for "Ç", and a dead key for each diacritic except the cedilla; so that "Á" is obtained by typing first the acute accent, then the letter "A".The same thing happens with computer keyboards, except when using an "English – International" keyboard layout, where to type "Ç" one should first type the acute accent and then the letter "C".The Brazilian keyboards are specified in the ABNT NBR ("Norma Brasileira Regulamentadora") 10346 variant 2 (alphanumeric) and NBR 10347 (numeric portion) standards.
