2.1.1 Keyboard

With a simple site, if your web pages are coded correctly, this criterion shouldn't pose too many problems. For the most part, the tab order just follows the order in the html code. However, the more additional features your site has, the more difficult this might be. The criterion states:

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.

How do you keyboard navigate

Fortunately, this is a criterion that you can easily test for yourself. You might even develop a preference for using a keyboard rather than a mouse to navigate.

Key strokes for navigation
Key Action Notes
TAB Moves through interactive elements on the page Any item that you can use a mouse to interact with, should appear when tabbing through.
SHIFT + TAB Moves backwards through interactive elements This is useful if you realise you have missed something and want to go back.
ENTER Activates a link or button, or selects an option Commonly used for SUBMIT buttons, e.g. to enter login details.
SPACE Activates a button, checks/unchecks a checkbox, expands a dropdown menu Drop down menus can be problematic, so it is worth checking this one carefully.
UP and DOWN arrows Moves through radio button options, menu options and autocomplete options; moves up and down the content by line If you want to go up or down the page very slowly, this is the best option.
SPACE or SHIFT + SPACE Scroll up or down by page This is useful for moving up or down the page without missing any information.
ESC Closes a dialogue box Use carefully as it can close things you might not want to close.

There are additional keystrokes for navigating applications such as Word and PowerPoint. These will be addressed separately. There are also keyboard shortcuts for performing common actions such as save, copy and paste.
