ISO/IEC 9995

ISO / IEC 9995 Information technology - Keyboard layouts for text and office systems (Information technology - Keyboard layouts for text processing and office systems ) is a series of international standards on which the data and build national standards such as the DIN standard DIN 2137 keyboard text input.

The series of standards established in 1994 and since then has undergone numerous updates. It consists of the following individual international standards:

  • ISO / IEC 9995-1:2009 General principles governing keyboard layouts
  • ISO / IEC 9995-2:2009 Alphanumeric section
  • ISO / IEC 9995-3:2010 Complementary layouts of the alphanumeric zone of the alphanumeric section
  • ISO / IEC 9995-4:2009 Numeric section
  • ISO / IEC 9995-5:2009 Editing and function section
  • ISO / IEC 9995-7:2009 Symbols used to represent functions
  • ISO / IEC 9995-8:2009 Allocation of letters to the keys of a numeric keypad

(ISO 9995-6:2006 Function section was withdrawn on 8 October 2009. )

ISO / IEC 9995-3

ISO / IEC 9995-3:2010 defines a secondary group of characters ( "common secondary group" ) for alphanumeric keyboards. The characters in this group are shown on the right half of the key area; the standard specifies their positions fixed irrespective of prevailing in the primary layout characters. For example, the yen symbol "¥ " is always displayed on the upper- position of the 6 character key in the second row from the top, ie with QWERTY keyboards such as the German occupation on the "Z " button on QWERTY keyboards such as the however, the U.S. occupation on the "Y" button.

In addition, the standard " no longer current secondary character group " defines a ( "outdated common secondary group" ) solely for compatibility purposes. This corresponds to the 9995-3:2002 defined in the previous standard version ISO / IEC "common secondary group".

The diacritical marks in the "common secondary group" are dead keys, ie they are entered before the basic letters. This applies also for consequences of several diacritical marks, such as those are required to enter the Vietnamese texts.

Furthermore, defined ISO / IEC 9995-3:2010 a list of " special characters that can be entered as a combination with diacritics " ( " Peculiar Characters Which can be Entered as Combinations using diacritical marks" ). This list contains combinations of one another and diacritical characters. For example, the inequality sign "≠" (Unicode U 2160 ) are entered. Especially letters with a horizontal slash ( such as Serbo-Croatian Đ / đ or maltese H / H ) are entered by means of the placed on the "K" key " cross- deletion accent ".
