view the warning, caution, or note in its original appearance and functionality at any time
by selecting the icon.
c. A message title, when applicable, shall be horizontally centered one character cell height
below or to the immediate right of the icon.
3.5.1.6.4 Text. Text of warnings, cautions, or notes shall be displayed within the border. Messages
containing two or more paragraphs shall have a blank line between paragraphs.
3.5.1.6.5 Danger from several sources. When warnings or cautions exist in separate categories for the same
set of technical information, they shall be successively displayed in decreasing order of severity: Warnings
irst, followed by cautions. Warnings or cautions in the same category shall be successively displayed.
However, there shall be no requirement to determine an order of importance within the same category.
When related warnings or cautions of the same category exist for the same block of technical information, it
is permissible to group them within a common border but they shall be visually distinct. In such a
case the title shall indicate the combined danger.
3.5.1.7 Indication of classiied information. Whenever classiied information is displayed, an indication of
the classiication level shall be indicated in the footer area (see 3.5.1.3 and igure 4). The indication shall
be the upper case spelling of the words corresponding to the classiication level, e.g., CONFIDENTIAL.
When color is available, these indications shall be displayed with a red background. Classiication
indications shall be clearly distinguishable from the function indicators in the same area. Technical
data developed using this speciication shall have security classiication markings in accordance with
DOD 5220.22-M and DoDM 5200.01.
3.5.2 User interaction functions. In addition to the common user interface functions previously described,
the presentation system software shall provide, as a minimum, the capability to activate the set of standard
functions for selecting, manipulating, accessing, navigating, and entering data into the system. These functions
shall be implemented as required by the presentation systems, e.g., one presentation device might have
dedicated keys for each standard function, another may provide software programmable function keys, a third
might use a pointing device to select the standard functions. The user shall be given the capability to
select and activate all of the standard input functions described herein.
3.5.2.1 Required navigation functions. A comprehensive set of commands to navigate and sequence through
the information shall be provided. The minimum set of navigation and control functions available and
common to all IETMs shall permit the minimum functionality as described in table III.
3.5.2.1.1 NEXT. The NEXT function shall display the next section or frame of information that the
user requires, based on context.
3.5.2.1.2 BACK. BACK shall be the opposite of NEXT. The BACK function shall display the previous
module or frame of information. The BACK function shall reset to the previous window information,
including all variables and settings. If relevant, a message box shall be presented explaining any special
circumstances which cannot be reversed by invoking the BACK function.
3.5.2.1.3 BROWSE BACK, BROWSE NEXT, and BROWSE EXIT. These functions shall be required
for all systems for which the NEXT and BACK functions set interactive system variables that are used
to effect subsequent navigation through the IETM. These navigation functions shall act as NEXT and
BACK, but shall not set or reset system variables automatically or through dialogs. Once either BROWSE
BACK or BROWSE NEXT is selected, other navigation functions shall not be available until the user
returns to the originating window by invoking the BROWSE EXIT function. The presentation system
shall provide a distinct visual indication that the system is in browse mode. When either the BROWSE
BACK or the BROWSE NEXT function is not logical, such as at the beginning of a string or at a
mandatory branch point, only the complementary BROWSE function shall be active. System variables shall
still be set and shall be activated and logged to a temporary state table. It is not necessary to post
system variables to the permanent state table when in browse mode.
3.5.2.1.4 RETURN. The RETURN function shall restore the location prior to branching. Pressing
RETURN shall perform an orderly exit from the branched information presentation, resetting all temporary
