Final answer:
The claim that a List Editor can edit a field value in a list by opening the record is true. It allows for quick modifications within the list view, enhancing the data management process.
Step-by-step explanation:
The statement that the List Editor allows a field value to be edited in a list by opening the record is true. In the context of software applications, particularly those that manage data like databases or content management systems, a List Editor is a tool that lets users modify records directly within a list. This means that you do not have to open each individual record in a separate form to change its value. Instead, you can quickly make edits to multiple entries within the list view itself, which streamlines the data management process and saves time.
