Abstract

Overview

ISO/IEC 9995-12:2020 - Information technology - Keyboard layouts for text and office systems - Part 12: Keyboard group selection - specifies standardized mechanisms to choose between keyboard groups used for multilingual and multiscript input. It is intended for environments where key-top markings can be dynamically displayed (physical keyboards with dynamic labels or on‑screen keyboards). The standard defines a compact, keyboard-driven method to switch collections of characters (groups) without relying solely on graphical menus.

Key topics and requirements

Superselect sequence: A defined sequence to begin group selection - typically the Level 3 select key (often labelled AltGr or Alt) combined with Tab. If no Level 3 key exists, an alternate key must be specified by the implementation.
Terminating sequence: Selection is confirmed by the Return key.
Selection tokens: After the superselect sequence, groups can be chosen using specified selection characters:
- Hyphen-minus (-) + ISO/IEC 15897 registration number (LC_KEYBOARD)
- Full stop (.) + OS-provided keyboard name
- Solidus (/) + file name or URL referencing a keyboard spec (ISO/IEC 24757 format recommended)
- Plus sign (+) + digit to define a quick‑reference slot followed by one of the above identifiers
- Single digit to recall a previously defined slot
- Backspace to revert to the previous keyboard
- Space to revert to the system default keyboard
- > and `
