Why is keyboard navigation important?

This is why keyboard navigation is one of the most important things to check. Keyboard navigation uses the TAB, Arrow, ENTER, and space bar keys. The TAB key allows a user to jump from one interactive element to another. Links, form fields, menus, and media player controls are all possible to navigate with the TAB key.

How can the keyboard be used to navigate your device's features?

Start from the beginning of your app and instead use the direction controls (arrow keys on the keyboard) to navigate your app. From each focusable element in your UI, press Up, Down, Left, and Right. Look for any instances in which the focus moves in a way you don't expect.

Are keyboard shortcuts accessible?

Keyboard shortcuts are a standard accessibility feature of most operating systems. Microsoft and Apple, for example, have standardized these keyboard shortcuts to make it easier to access menus and functions quickly, without having to use a mouse.
