How do screen readers navigate within lists of items?

Screen readers primarily use arrow keys to navigate within lists of items. This method allows users to move through the items one at a time in a controlled manner, enabling them to listen to each option and decide how to interact with it. The up and down arrow keys allow users to move through the list efficiently, while features like announcing the currently focused item or providing context about the number of items can enhance the experience.

When users press the up arrow, they move to the item above the currently focused item, and similarly, the down arrow moves them to the item below. This direct navigation is particularly important for maintaining accessibility, as it gives users the opportunity to absorb information about each item without losing their place in the list.

Other methods of navigation, such as using Page Up and Page Down or Tab, are not as effective for list navigation because they can jump large distances, leading to a disjointed experience. Enter is typically used to activate or select an item, rather than for the purpose of navigating through a list. Thus, the arrow keys represent the most intuitive and user-friendly method for managing navigation within lists for individuals using screen readers.
