Diacritic mark

Generation with computers

Depending on the keyboard layout and keyboard mapping, it is more or less easy to enter letters with diacritics on computers and typewriters. Keyboards used in countries where letters with diacritics are the norm, have keys engraved with the relevant symbols. In other cases, such as when the US international or UK extended mappings are used, the accented letter is created by first pressing the key with the diacritic mark, followed by the letter to place it on. This method is known as the dead key technique, as it produces no output of its own but modifies the output of the key pressed after it.
