In case anyone is interested in what ISO 9995 key coordinates are:
The grid of a keyboard is defined in ISO/IEC 9995-1. Row A is the row
of the SPACE BAR. Row E is the row where the digit 1 key in the
alphanumeric section of a keyboard (there is also a numeric section on
many keyboards, the numeric keypad) is generally located on QWERTY,
QWERTZ and AZERTY keyboards.
Number coordinates go from left to right, the location of the number 1
in the same alphanumeric section being the relative reference for
coordinate 1. Coordinate 0 refers to the key to the left of the digit
1, if any. As in general keys are arranged slanted from row to row,
the same numbered key on a lower row is in general slightly to the
right of the row above (on QWERTY, QWERTZ and AZERTY keyboards, the
letter E is refered as D03).
The full name of the standard is
ISO/IEC 9995:1994, Information technology -- Keyboard layouts for
text and office systems.
It has the following parts:
Part 1: General principles governing keyboard layouts
Part 2: Alphanumeric section
Part 3: Complementary layouts of the alphanumeric zone of the
alphanumeric section
Part 4: Numeric section
Part 5: Editing section
Part 6: Function section
Part 7: Symbols used to represent functions
Part 8: Allocation of letters to the keys of a numeric keypad
