Which of the following choices accurately describes the IETM's underlined "dashed" words?

The term "dashed" words in the context of an Interactive Electronic Technical Manual (IETM) refers to "hotspots." Hotspots are interactive elements within the IETM that allow users to engage with the content in a meaningful way. When a user clicks on these designated areas, it typically provides additional information, navigates to related sections, or activates certain functions within the software. This interactivity is crucial in making the IETM more user-friendly and enhancing comprehension by offering quick access to supplementary data or guidance relevant to the topic at hand.

The other options, while related to forms of interaction or information within technical manuals, do not capture the specific essence of “dashed” words as defined by the functionality and purpose of hotspots. Interactive commands may denote a type of user input, reference indicators could indicate specific citations or sources of further information, and highlighted features generally emphasize important text but do not imply interactivity. Hotspots, however, uniquely convey a direct interaction point that enriches the user experience in navigating the IETM.
