ISO/IEC 9995-6:1994

Within the general scope described in part 1, this part of ISO/IEC 9995 specifies the function section of a keyboard and the division of that section into zones. This part of ISO/IEC 9995 specifies the arrangement, the number, and the location of the keys in the func­tion zones of the function section as well as the allo­cation of functions to the keys.  The first edition of this part of ISO/IEC 9995 does not allocate functions, except for the control function Es­cape, to the keys of the function section.  Functions allocated to keys in other parts of ISO/IEC 9995 are defined in those parts.
