摘要： Keyboard apparatus is described in which a keyboard having dead-keys to enable accented characters to be entered is claimed. A storage means, preferably of read only type, is divided into a number of sections; each section contains character codes representing accented or non-accented characters associated with that section. When a given dead key is activated, this addresses a section of the store associated with that dead-key to access the section containing the characters which are accented with the accents associated with that dead key. Activation of the next character key causes accessing of the code for an accented character within that section. Different accents for the same or other characters can be associated with different dead keys. Optionally the store can be arranged to store only validly-accented characters, thus avoiding the entry of invalidly-accented characters. Non-accented characters are normally accessed from a single section of the store. Common accented characters do not require dead-key operation.
