accesskey attribute value must be unique

All accesskey attribute values in a document must be unique. Put another way, accesskeys must not be repeated to prevent unexpected effects for keyboard users.

Specifying a accesskey attribute value for some part of a document allows users to quickly activate or move the focus to a specific element by pressing the specified key (usually in combination with the alt key). Duplicating accesskey values creates unexpected effects that ultimately make the page less accessible.

For each defined accesskey, ensure the value is unique and does not conflict with any default browser and screen reader shortcut keys.

Content is not operable by keyboard users with no or low vision who cannot use devices such as mice that require eye-hand coordination, users who have trouble tracking a pointer, or users who must use alternate keyboards or input devices acting as keyboard emulators.
