What attribute provides a "hot-key" combination to focus on a component?

The accesskey attribute is specifically designed to provide a keyboard shortcut, or "hot-key," for focusing on a component within a web page. When this attribute is assigned to an HTML element, it allows users to activate that element using a designated key combination, enhancing accessibility and usability for individuals who prefer using the keyboard over a mouse.

By using the accesskey, users can quickly navigate to specific parts of a web page or trigger actions without needing to rely solely on the standard tabbing order or mouse interaction. This is particularly beneficial for those with disabilities or those who use assistive technologies that translate keyboard inputs.

While the tabindex attribute does play a role in controlling the order of keyboard navigation through elements, it does not create a specific hot-key combination for direct access. The focus attribute, on the other hand, is not a valid HTML attribute for elements but could refer to programmatically forcing focus onto an element. The value attribute is used to specify a value for input elements and is not related to hot-key combinations. Therefore, the accesskey attribute is the most appropriate choice for this functionality.
