deselect that item. The user shall be provided with the capability to select a single item, a range of items,
or additional non-contiguous items, including multiple ranges of items. Selecting the OK function will
end the selection process. If a user is required to select only one option, the SELECT function shall
activate the item without requiring the OK function.
3.4.1.1.2 Movement. The cursor shall be capable of moving from one selectable information item to
another, such as, from cell to cell in a table, from selectable word to selectable word in text, or from
selectable object to selectable object in a graphic. If a free-form positioning device, e.g., mouse, is not
provided, the capability to use the UP, DOWN, LEFT, and RIGHT functions to allow movement of the
cursor to any selectable region shall be provided.
3.4.1.1.3 Shapes. Each cursor mode shall use clearly discernable shapes or icons.
3.4.1.1.4 Tab groups. When several sets of selectable objects are displayed, they shall be formed into ields
called "tab groups". Cursor movement (and associated focus for any input) shall be constrained within a single
tab group. The TAB function shall allow a forward sequential movement of the cursor between tab groups.
The BACK TAB function shall allow a reverse sequential movement of the cursor between tab groups.
Examples of tab groups are: individual ill-in-the-blanks, groups of related choices, and dialog push buttons.
3.4.1.1.5 Pointer. If the system provides a free-form positioning device it shall have a position designator
(pointer) and a POINTER SELECT function. The pointer shall be used in conjunction with the cursor. The
pointer shall be used to rapidly relocate the cursor on the display. The system shall provide the capability to
move the cursor and select items with the pointer.
3.4.1.2 Windows. A window shall be an area of the screen that displays information and provides the
functional means to communicate with the IETM. The presentation system shall have the capability to
display a minimum of three windows on the screen at one time, but only one window shall be active at any
one time. An active window shall be designated by a highlighted title bar. The system shall provide the
capability to open and close windows. The system shall allow windows to be displayed overlapping, adjacent
(tiled), and cascading (overlapping with title bars showing). If a single window device is speciied by the
acquiring activity, the IETM shall restrict the use of multiple windows (see 6.2o).
3.4.1.2.1 Presentation. The minimum window shall be composed of client area, title bar, menu bar,
systems (see 3.4.1.2).
3.4.1.2.2 Client area. The client area shall be the portion of the window in which the IETM content
information is displayed. The client area shall be contained within the window frame and include one or
more data panes or viewing areas displaying the text, tables, graphics, etc., of the IETM information.
The IETM contents shall be displayed in the client area (see 3.5.1).
3.4.1.2.3 Title bar and menu bar. The top area of every window shall consist of a horizontal title bar and a
menu bar that, when displayed, appears immediately below the title bar. The title bar shall contain the title of
the information being displayed. The title shall be displayed in uppercase letters. The menu bar (see 3.4.1.3)
shall appear only at the user's request. The title bar shall be highlighted when the window is active. When the
single window option is speciied by the acquiring activity (see 6.2o), the title bar shall be capable of being
toggled on and off with a menu bar (see 3.4.1.3.5.1). In this case, the title bar shall be initially displayed at
the top of the window and the menu bar shall replace the title bar display when toggled (see igure 1).
3.4.1.2.4 Window controls. Whenever the information to be displayed requires a space larger than the
available window area, the user shall be given the capability to manipulate the displayed information or
window using the following window controls. The need for this capability shall be minimized.
3.4.1.2.4.1 Scroll bars. Vertical and horizontal scroll bars shall provide the capability to SCROLL UP,
SCROLL DOWN, SCROLL LEFT, and SCROLL RIGHT to manipulate the displayed information (text,
graphic, table, etc.). Scroll bars shall appear at the bottom of the data pane and at the right edge of the
data pane with arrow marks at each corner. Scroll bars shall have the following components: a scroll region
which is the background of the scroll bar and represents visually the length of the area that can be scrolled;
