+<h2>Why is this an issue?</h2>
+<p>The <code>accesskey</code> attribute, despite its potential utility, is fraught with numerous issues that limit its effectiveness and
+usability:</p>
+<ul>
+ <li> Screen readers' implementation of <code>accesskey</code> largely depends on the browser used, as they rely on browsers for much of their
+ functionality. Some screen readers may repeatedly indicate the <code>accesskey</code> value each time the element is encountered, potentially
+ causing unnecessary repetition and noise for the user. </li>
+ <li> Conflicts between <code>accesskey</code> shortcuts and other keyboard shortcuts, such as those of browsers, operating systems, assistive
+ technologies, or browser extensions, are frequent. This overlap can lead to uncertainty and potentially trigger unintended actions, causing user
+ confusion. </li>
+ <li> While keyboard shortcuts are vital for screen reader functionality, conflicts can disable either the screen reader or <code>accesskey</code>
+ shortcuts. Typically, screen reader shortcuts take precedence, disabling the <code>accesskey</code> but preserving screen reader functionality.
+ However, this can cause confusion for users attempting to activate an <code>accesskey</code>. </li>
+ <li> No keystroke combinations can guarantee zero conflicts with all browsers, assistive technologies, or operating systems, particularly
+ considering foreign languages. For instance, an <code>accesskey</code> shortcut that works in an English browser may conflict in the same browser
+ set in another language due to different menu naming conventions. </li>
+ <li> While using numerals instead of letters for keyboard shortcuts could reduce conflicts, it’s not a foolproof solution. There’s no standard
+ correlation between numbers and web functions, which could lead to user confusion. </li>
+ <li> Unlike the Windows environment that highlights keyboard shortcuts in menus, web pages or applications lack a standardized method to notify
+ users about available <code>accesskey</code> shortcuts. </li>
+</ul>
+<p>Given these concerns, it is generally recommended to avoid using `accesskey`s.</p>
+<pre data-diff-id="1" data-diff-type="noncompliant">
+function div() {
+ return &lt;div accessKey="h" /&gt;;
+}
+</pre>
+<p>Do not use `accesskey`s at all.</p>
