What does the status bar display?

The status bar is a user interface element that provides pertinent information about the current state of a software application, typically at the bottom of the window. It displays document details such as the current page number, word count, or zoom level, as well as view options that allow users to quickly assess characteristics of their document. This functionality enhances user experience by providing immediate feedback about the context and configuration of the work being done, enabling better navigation and management of tasks.

The other choices pertain to different aspects of software functionality: file editing options and shortcuts relate more to toolbars and menus; system error messages are generally shown as pop-up alerts; and network status might be indicated in system trays or other areas, but not primarily in the status bar. Thus, the correct answer about what the status bar displays is indeed centered around document details and view options.
