ISO 9995

ISO/IEC 9995 "Information technology -- Keyboard layouts for text and office systems" is a standard defining layouts of computer keyboards. The standard has eight parts.

ISO/IEC 9995 defines a keyboard as having three groups of key assignments:

• Group 1 is the basic layer with a base and shift (lower and upper case)
• Group 2 is the national layer with a base and shift. There is a locking shift to access this.
• Group 3 allows for supplemental characters to be entered. This is a single plane and uses a non-locking shift.

The standard has eight parts (these are for sale only, but see also additional links below):
