Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized System for worldwide standardization. National bodies that
are members of ISO or IEC participate in the development of International Standards through
technical committees established by the respective organization to deal with particular fields of
technical activity. Other international organizations, governmental and non-governmental, in
liaison with ISO and IEC, also take part in the work.
In the field of information technology, ISO and IEC have established a joint technical committee,
lSO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are
circulated to national bodies for voting. Publication as an International Standard requires
approval by at least 75% of the national bodies casting a vote.
International Standard lSO/IEC 10741-1 was prepared by Joint Technical Committee lSO/IEC
JTC 1, Information technology.
lSO/IEC 10741 consists of the following Parts under the general title information technology -
User System interfaces - Dialogue interaction:
Part 1: Cursor control for text editing
Part 2: Cursor control for Spreadsheets
Annex A of this part of lSO/IEC 10741 is for information only.

Introduction
This part of lSO/IEC 10741 specifies how incremental cursor control is effected as a result of user
interaction with a text editor. Cursor control in form filling and spread sheet applications, cursor
control in editing other forms of text such as graphics, and cursor control in manipulating simple
and complex documents are not covered in this part of lSO/IEC 10741.
The clauses in this part of lSO/IEC 10741 are basic to a set of proposed Standards dealing with
user/computer dialogue interaction.
The specifications in lSO/IEC 10741 are consistent with the three ways in which text editing data
may be considered:
-
the internal data structure (the internal Computer storage),
-
the displayed data (the interface presented by the Computer System to the User),
and
-
the conceptual data structure (the user’s interpretation of what is presented).
Cursor control identifies and changes the location of user/system interaction through a Change
in focus. The accurate and appropriate mapping of the user’s focus and intent to the active
Position displayed by the System and the processing of the internal data structure is the objective
of cursor display and control. The ease of changing the focus and the predictability of the results
are central to the user’s comfort level and sense of control.
Some text editors implement formatting controls that are patt of the text string in the internal data
structure and that are displayed or available to be displayed to the user as a part of the
displayed data. Other text editors implement formatting control as a separate function that
creates a template controlling the output of the text string. The specifications in this part of
lSO/lEC 10741 permit both types of formatting control implementation.

Part 1:
Cursor control for text editing
1 Scope
This part of lSO/IEC 10741 defines how a number of System capabilities for cursor control in text
editing Systems shall be initiated, controlled, and monitored by users by means of cursor control
functions. lt covers bounded linear text and open page text mode editing.
The scope of this patt of lSO/IEC 10741 is limited to text editing of left-to-right writing styles by
use of keyboard keys or other input devices, but the principles delineated may be applicable to
text in other scripting styles. Cursor control in right-to-left and top-to-bottom writing styles may
be the subject of future standardization.
This part of ISO/IEC 10741 applies only to information Systems that display text to a user for

specifying a harmonized and consistent User interface.
2 Conformance
An application claiming conformance to this part of lSO/IEC 10741 shall conform to clauses 5,
6, and 7.

4 Definitions
For the purposes of this patt of lSO/IEC 10741, the following definitions apply.
4.1 active document: Document that contains the current cursor or selection marker. lt is a
(possibly empty) body of text that is ready to receive input.
4.2 active Position: Character Position that will display the graphic Symbol representing the next
graphic Character, or relative to which the next control function [l] will be executed ,
Note - The external indication of the active Position in an active document is the cursor.
4.3 beginning of line: First Position of the line that could be occupied by a graphic Character.
4.4 between-objects cursor: Cursor that visibly identifies the boundary immediately Prior to the
active position.
4.5 bounded linear text mode: Mode in which it is only possible to move the cursor among
existing characters or formatting or presentation indicators, within the active document. For
example, the cursor cannot be moved beyond the last Character of a line.
4.6 Character: Member of a set of elements used for the organization, control, or representation
of data [2].
4.7 Character path: Sequential Order of Character positions along a line of presented data [2].
4.8 co-located cursor: Cursor that occupies the active position.
4.9 cursor: Special indicator used in a display to mark the active position.
Note - The word “cursor” should not be confused with “pointer,” which is reserved for indicating the Symbol
controlled by the mouse or other input device to Change the Point of focus (for example, the cursor) on a
graphical user interface [3].
4.10 editing: Modification of content or layout of text. Editing processes include creation,
insertion, deletion, and re-arrangement of text.
4.11 end of line: 1) In bounded linear text mode the Character Position after the last graphic
Character or formatting or presentation indicator. If the line is empty, the end of line is the Same
as the beginning of line. 2) In open page text mode, the last Position in the line that could be
occupied by a graphic Character.
Note - A carriage return, and a Software carriage return that is automatically inserted by a text editing System
