Always allow user control for media and navigation. Ensure all content can be navigated with a keyboard.
Why this matters...
Allow media control
You should never force media to play, or stop users from having control of play, pause, stop, volume and captions.
The ability to use a keyboard is essential for web accessibility. You should ensure you have a visual indicator for the element that has keyboard focus and check your navigation order is logical.
Never rely on specific input
Learners may be using a touch screen, a mouse, keyboard navigation or other assistive technology. Never force use of one specific type of input device.

Never make assumptions about the way your users navigate and use electronic devices. Keyboard control, for example, is essential for users that struggle with fine motor control or have limited (or no) use of their hands. Ensuring keyboard accessibility usually ensures other specialist peripheral devices like eye trackers, voice navigation and braille keyboards also work. You need to pay close attention to the navigation order, especially in tools like PowerPoint where objects are placed in a non-linear format.
