Visually Impaired users often use a keyboard to navigate a website or application. One of the best ways to improve the accessibility of your website or application, is to ensure it can be navigated with a keyboard.
Including keyboard navigation testing in the testing routine will significantly improve your application and website, with minimal additional effort.
