Providing enhanced functionality in an interactive electronic technical manual

6) An apparatus for highlighting units referenced in technical documentation for an item via an interactive electronic technical manual system (IETM) configured to provide electronic and credentialed access to the technical documentation for the item via an IETM viewer, the apparatus comprising at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to:

• provide a window for display via the IETM viewer executing on a user computing entity being used by a user signed into the IETM, the window comprising (1) a first view pane displaying textual information referencing one or more units and (2) a second view pane displaying media content illustrating the one or more units as selectable in which the window is configured to display the first view pane and the second view pane on non-overlapping portions of the window;
• receive input of a selection of a portion of the textual information displayed on the first view pane comprising a first unit of the one or more units, wherein the selection of the portion of the textual information is performed by a user via the IETM viewer;
• responsive to receiving the input of the selection of the portion of the textual information, cause the first unit to be displayed as highlighted in the media content on the second view pane;
• receive input of a selection of a second unit of the one or more units displayed in the media content on the second view pane, wherein the selection of the second unit of the one or more units is performed by the user via the IETM viewer;
• and
• responsive to receiving the input of the selection of the second unit of the one or more units, cause each reference to the second unit in the textual information to be simultaneously displayed as highlighted in the textual information on the first view pane.

11) A non-transitory computer storage medium comprising instructions for highlighting units referenced in technical documentation for an item via an interactive electronic technical manual system (IETM) configured to provide electronic and credentialed access to the technical documentation for the item via an IETM viewer, the instructions being configured to cause one or more processors to at least perform operations configured to:

• provide a window for display via the IETM viewer executing on a user computing entity being used by a user signed into the IETM, the window comprising (1) a first view pane displaying textual information referencing one or more units and (2) a second view pane displaying media content illustrating the one or more units as selectable in which the window is configured to display the first view pane and the second view pane on non-overlapping portions of the window;
• receive input of a selection of a portion of the textual information displayed on the first view pane comprising a first unit of the one or more units, wherein the selection of the portion of the textual information is performed by a user via the IETM viewer;
• responsive to receiving the input of the selection of the portion of the textual information, cause the first unit to be displayed as highlighted in the media content on the second view pane;
• receive input of a selection of a second unit of the one or more units displayed in the media content on the second view pane, wherein the selection of the second unit of the one or more units is performed by the user via the IETM viewer;
• and
• responsive to receiving the input of the selection of the second unit of the one or more units, cause each reference to the second unit in the textual information to be simultaneously displayed as highlighted in the textual information on the first view pane.
