Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see HYPERLINK "http: //www .iso .org/directives"www
.iso .org/directives).
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see HYPERLINK "http: //www .iso .org/patents"www .iso
.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

Introduction
Many keyboard layouts are used over the whole world. This part of the ISO/IEC 9995 series of standards
specifies a way to navigate between keyboard groups, so a user can use more than one collection of
characters, for example to write text in more than one language, or input names of persons or places in
different scripts.
Many graphic operating environments offer a way to click on an icon to change the keyboard group.
This document offers an alternative way to change keyboard group in a few keyboard strokes, and in a
standardized way only using characters that are widely available on keyboards in the world.
This document is initiated by the work in ISO/IEC TR 15440:2016 Information technology -- Future
keyboards and other input devices and entry methods.

Part 12:
Keyboard group selection
1 Scope
This document specifies mechanisms to choose between the keyboard groups specified in other
ISO/IEC 9995 parts, national keyboards standards, or other keyboard definitions.
These mechanisms primarily become useful when the stipulated marking on the key top can be
displayed by technology such as OLED.

group
logical state of a keyboard providing access to a collection of graphic characters or elements of graphic
characters whose subsets are called levels.
Note 1 to entry: A group gives access to one collection of characters. Typically, when more than one language is
