A document's `accesskey` attribute values must all be distinct. Or, to put it another way, `accesskeys` must not be used more than once to protect keyboard users from unpleasant surprises.

When a document's `accesskey` attribute value is supplied, users can quickly activate or switch the focus to a particular element by hitting the designated key (often in tandem with the `alt` key). The page becomes less accessible as a result of duplicating the values for the `accesskey` attribute.

Make sure the value of each defined `accesskey` is distinct and does not interfere with any screen reader or default browser shortcut keys.

Users who must use alternative keyboards or input devices serving as keyboard emulators, users who have problems tracking a pointer, or users who are blind or have low eyesight and cannot employ eye-hand coordination-required devices like mice, cannot operate the content.

<h3>What this Accessibility Rule Checks</h3>

Makes certain that every element on the page with an `accesskey` attribute has a different value.
