What method can candidates use for onscreen references navigation?

The correct choice highlights the practicality and efficiency of using a cursor to navigate onscreen references. Dragging the cursor on a designated icon allows users to interact directly with the interface, providing a tactile way to select and access information quickly. This method can enhance usability, particularly in complex systems or software, where visual cues and iconography play a significant role in guiding the user.

The other methods can have limitations. Sole reliance on keyboard shortcuts may exclude users who are more visually oriented and prefer a graphical interface. Using arrows on the screen could suggest a more restricted form of navigation, possibly limiting the ability to browse through various onscreen elements efficiently. Voice commands, while innovative, may not always be practical in environments where background noise is prevalent or where software does not support voice recognition effectively. Thus, the ability to drag the cursor on an icon encompasses a user-friendly approach that is widely applicable across various scenarios.
