What is “Keyboard Compatibility”?

All functionality must be usable with the keyboard. That is, users can access and move between links, buttons, forms, and other controls using the Tab key and other keystrokes. Websites should not require a mouse; for example, pop-up calendars should also let users type in a date.

Who depends on this feature?

What are the additional benefits?

What needs to happen for this to work?

Native HTML controls, like links, buttons, and form elements, work with the keyboard by default and should be used where possible. Custom-made controls, CSS styles, and scripts that control interaction may need additional coding for keyboard compatibility. Ensure that the tab order is logical, to allow keyboard navigation around the content and controls. Provide a way for users to jump between blocks of content and controls. Keyboard issues occur particularly in forms, menus, and applications with many controls.

or simply a broken mouse,
the result is the same:
The man with the wheelchair also cannot use the site.
Websites and apps need to be operable by keyboard. He switches to a different website that allows typing the date.
