In LexisNexis, what action should you take to view only a portion of a document?

Choosing to click on "Custom" in LexisNexis allows you to tailor the display of the document to only show specific sections or portions you are interested in. This feature is useful for narrowing down content, especially when you are seeking targeted information without the need to sift through the entirety of the document. Customizing the view can enhance efficiency in research activities by letting you focus on relevant details quickly.

Other options, such as selecting the document’s title or expanding the full document view, would generally present the complete text of the document rather than a portion. Similarly, requesting a summary report typically provides an overview of the document but does not allow for the selective viewing of specific sections within the original text. By using the "Custom" feature, you achieve a more manageable and focused reading experience.
