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 9995-8:2009 specifies the allocation of letters to the keys of the numeric zone ZN0 of a keyboard which has the ten digits zero to nine allocated in the 1-2-3 layout. The layout specified in ISO/IEC 9995-8:2009 is intended for applications of information technology equipment keyboards where letters instead of digits are used for the mnemonic retention of numeric information.
