Keyboard Testing

2.1.1 Keyboard: All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes, except where the underlying function requires input that depends on the path of the user’s movement and not just the endpoints. (Level A)

Note 1: This exception relates to the underlying function, not the input technique. For example, if using handwriting to enter text, the input technique (handwriting) requires path-dependent input but the underlying function (text input) does not.

Note 2: This does not forbid and should not discourage providing mouse input or other input methods in addition to keyboard operation.

Keyboard access to a website is key to the usability of your site. All interactions and information that can be accessed with a mouse must be accessible with just a keyboard. This doesn’t mean everyone who can’t use a mouse will use a keyboard, but alternative AT inputs use keyboard-like inputs to navigate the web.

With Full Keyboard Access, you use the Tab key and arrow keys to navigate to items on the screen, and the Space bar to select an item.


Keyboard accessibility is NOT enabled by default on a Mac.

Follow these steps to turn on Full Keyboard Access:
Choose Apple menu > System Preferences, then click Keyboard.

  • Click Shortcuts.
  • To navigate only to text boxes and lists on the screen, select “Text boxes and lists only.” To enable Full Keyboard Access and navigate to all controls on the screen, select “All controls.
