ISO/IEC 9995定义了一个框架，用于在当今和未来最广泛的使用键盘的应用程序中，所有字母数字和数字键盘的布局。键盘要执行的功能分为三类，分别对应于键盘的主要物理部分。 ISO/IEC 9995在键盘设计中的应用将为用户提供统一、可预测的用户-机器界面，方法是将键盘划分为功能区域和部分，并将功能分配给按键。 ISO/IEC 9995-7:2009定义了任何类型的数字、字母数字或复合键盘上的功能符号。这些符号中的每一个都被认为是通用的和非通用的- 与语言相关的功能名称的等价物。功能名称和描述用英文和法文给出。

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. ISO/IEC 9995-7:2009 defines symbols for functions found on any type of numeric, alphanumeric or composite keyboards. Each of these symbols is intended to be considered as universal and non-language related equivalent of names for the function they represent. Names of functions and descriptions are given in English and French.
