Which feature allows a search to be case-sensitive in a dialog?

The case sensitive check box is the feature that enables a search to be case-sensitive in a dialog. When this option is selected, the search functionality will distinguish between lowercase and uppercase letters. This means that if the user searches for "apple," it will not return results that include "Apple" or "APPLE." This functionality is particularly useful when dealing with text where the case of the characters is significant, such as distinguishing between variable names in coding or differentiating between proper nouns and common nouns in a script.

Other options, while they may enhance or alter the search experience, do not specifically address the need for case sensitivity in searches. The wildcard option typically involves using symbols to represent unknown characters in a search, which does not relate to case sensitivity. The Quick Find button generally initiates a straightforward search without specific settings for nuances like case sensitivity. Advanced search settings could offer more refined search parameters but do not specifically highlight the case sensitivity setting as directly as the check box does.
