What defines a "keyboard interaction pattern" in accessibility?

A "keyboard interaction pattern" in accessibility encompasses the established methods and rules by which keyboard keystrokes are utilized and interpreted for various Accessible Rich Internet Applications (ARIA) widgets. These patterns are essential for ensuring that users who rely on keyboards for navigation and interaction can effectively use web content.

Keyboard interaction patterns provide guidance on how to implement keyboard navigation, including which keys should be used for specific actions and how those actions correspond to ARIA roles and properties. For instance, certain keystrokes may trigger opening a menu, moving focus to different elements, or activating buttons—all of which must be defined clearly to enhance accessibility.

This focus on keyboard interactions is critical because not all users can or prefer to use a mouse. Understanding and implementing these patterns allows developers to create a more inclusive experience that accommodates a broader range of abilities and preferences, ensuring compliance with accessibility standards.
