Information technology — Keyboard layouts for text and office systems — Part 3: Complementary layouts of the alphanumeric zone of the alphanumeric section
ISO/IEC 9995 defines a framework for the layout of all alphanumeric and numeric keyboards across the widest spectrum of today's and upcoming applications using keyboards. The functions to be performed by keyboards are grouped into three categories that correspond to the main physical sections of the keyboard.
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.
lSO/IEC 9995-3:2010 defines the allocation on a keyboard of a set of graphic characters which, when used in combination with an existing national version keyboard layout or the complementary Latin group layout as defined in ISO/IEC 9995-3:2010, allows the input of a minimum character repertoire as defined by collection 281 (MES-1) specified in ISO/IEC 10646 and proposes extensions of this minimum repertoire.
