A data analyst in your organization cannot use a mouse due to a recent injury. Which feature should you implement in your Microsoft Power BI reports to assist her in navigating and interacting with them?

Implementing tab order in your Microsoft Power BI reports is an effective way to assist a data analyst who cannot use a mouse. Tab order allows users to navigate through interactive elements of a report using the keyboard's Tab key, enabling them to access buttons, filters, visuals, and other features in a sequential manner. This is particularly beneficial in providing a smooth and accessible navigation experience for individuals with mobility impairments or those who rely on keyboard navigation.

Other options serve different purposes. For instance, alt text is important for visually impaired users as it provides descriptions of visuals when using screen readers, but it does not aid navigation or interaction directly. Focus mode enhances the visibility of a report visual, helping users focus on one element, but it does not facilitate overall navigation throughout the report. High-contrast colors improve visibility and accessibility for users with visual impairments but do not enhance navigation capabilities.
