4.3

secondary group layout

allocation of the graphic characters of group 2 to the keys of a particular keyboard

4.4

key effect

effect that results when a key is actuated, depending on the active level, and possibly by the concurrent operation of a qualifier key or keys

4.5

lock state

4.8

control function

action that affects the recording, processing, transmission, or interpretation of data

4.9

group

logical state of a keyboard providing access to a collection of graphic characters or elements of graphic characters

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 can be arranged on several levels within a group.

Note 3 to entry: The input of certain graphic characters, such as accented letters, can require access to more than one group.

4.10

section

block of keys, mostly with some functional relationship

4.11

Note 2 to entry: In certain cases the level selected can also affect function keys.

4.12

active position

system to which the keyboard is attached, probably consisting of a processor and software to handle the keyboard and to run application programs

4.17

qualifier key

key whose operation has no immediate effect, but which, for as long as it is actuated, modifies the effect of other keys

Note 1 to entry: A qualifier key can be, for example, a level select key or a control key.

editing key

key whose primary purpose is the input of an editing function

4.19
