ISO/IEC 9995-2:2009
Information technology -- Keyboard layouts for text and office systems -- Part 2: Alphanumeric section
Product Details
Application of ISO/IEC 9995 in the design of keyboards will provide the user with a unified, predictable user-machine interface by dividing the keyboard into functional areas and sections and allocating functions to keys.
ISO/IEC 9995-2:2009 specifies the alphanumeric section of a keyboard and the division of that section into zones; the arrangement, the number, and the location of the keys in the alphanumeric zone ZA0 of the alphanumeric section; and the layout and allocation of several control functions to the keys in the function zones of the alphanumeric section.
The primary layout within the alphanumeric zone is established in most countries by a national standard or by national usage. ISO/IEC 9995-2:2009 provides allocation guidelines.
