### Why is this important?
Setting the `accesskey` attribute on elements allows quick access to the element by focusing or activating the element using the keyboard.
Having a unique `accesskey` value allows the user agents to determine which element to activate when a user triggers the access key.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* Update the `accesskey` attribute on the element with a unique non-empty value.
For example:
```
<button type="button" name="testButton1" id="button1" accesskey="a">Accept</button>
<button type="button" name="testButton2" id="button2" accesskey="r">Reject</button>
```
Note: The [4.1.1 Parsing](https://www.w3.org/WAI/WCAG21/Understanding/parsing.html) requirement was removed from WCAG.
However, the Checker will report an issue against another accessibility requirement when it detects it causes an accessibility issue.
