Motor impairment

Content does not restrict its view and operation to a single display orientation, such as portrait or landscape, unless a specific display orientation is essential (i.e., bank check). 

Make it easier for users to interact with added content. Tooltips, drop-down menus, and popups are examples of added content.

If keyboard shortcuts are implemented using only a letter (including upper- and lower-case letters), punctuation, number, or symbol characters, provide a way to turn off or remap character key shortcuts.

All operations must use simple gestures that need only a single touch. If the site or application does use multi-touch gestures, be sure to also provide simple interfaces. 

People with disabilities rely on interface controls that are used programmatically. These controls have a visual label, as well as a programmatic label, known as its Accessible Name.

Ensure that functions that are triggered by moving a device or by gesturing towards the device can also be operated by more conventional user interface components.

Media player accessibility is essential for video content. Evaluate the accessibility and cross-device compatibility of the media player that comes with your video-distribution platform.

It's important the search facility on your site is logically and conventionally placed and constructed for optimal accessibility.

It's important to provide consistent navigation regions to navigate between a site's pages and—where there is a lot content on each page—between sections of pages.

Autocomplete widgets can be helpful for accessibility because they can make it easier to enter text by providing suggestions based on the characters initially typed.
