Information technology — Keyboard layouts for text and office systems — Part 12: Keyboard group selection

This document specifies mechanisms to choose between the keyboard groups specified in the ISO/IEC 9995 series, national keyboards standards, or other keyboard definitions. These mechanisms primarily become useful when the stipulated marking on the key top can be dynamically displayed on the key top.

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.
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 document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC 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 www .iso .org/ patents) or the IEC
list of patent declarations received (see http:// patents .iec .ch).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Introduction
Many keyboard layouts are used over the whole world. This document 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 across the world.
This document builds on ISO/IEC TR 15440.

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
used, multiple groups are required.

Note 2 to entry: Usually these graphic characters or elements of graphic characters logically belong together and
may be arranged on several levels (up to 3) within a group.
Note 3 to entry: The input of certain graphic characters, such as accented letters, may require access to more
than one group.
Note 4 to entry: On physical keyboards, each group is normally labelled using a distinct column on a key, and
levels are stacked vertically within that column, except when stated otherwise in certain situations. On on-
screen keyboards, a group is normally shown one level at a time. There is usually a button to choose the group (or
language) and another button, or more, to choose the level.
3.2
level
logical state of a keyboard providing access to a subset of a collection of graphic characters or elements
of graphic characters which form a group
Note 1 to entry: Usually these graphic characters or elements of graphic characters logically belong together,
such as the capital forms of letters.
Note 2 to entry: In certain cases, the level selected may also affect function keys.
