Keyboard Navigation
Keyboard navigation means that all interactive elements of a website – links, buttons, forms, menus – can be reached and operated entirely without a mouse, using the keyboard alone.
In practice
A visible focus outline, a logical tab order and a working skip link to the main content are the central building blocks. Keyboard operation helps not only people with motor impairments, but also anyone working without a trackpad or dealing with a mouse that has stopped working.
