The HTML accesskey attribute defines a keyboard shortcut to activate or focus an element.
- It assigns a keyboard key combination to trigger an element (like a link or button).
- Browser support and specific key combinations vary (e.g., Alt + key on Windows, Ctrl + key on macOS).
- Use it sparingly and provide clear visual cues for accessibility.
Syntax
<element accesskey = "single_character"><!DOCTYPE html>
<html>
<body>
<a href="https://www.example.com" accesskey="e">Example Link (Alt + e)\
</a>
<button accesskey="s">Submit (Alt + s)</button>
</body>
</html>
- accesskey sets a keyboard shortcut (e.g., Alt + key).
- Text in parentheses shows the shortcut to users.
Shortcut to use accesskey
The table describes the shortcut to use Accesskeyy:
| Browser | Windows | Mac | Linux |
|---|---|---|---|
| Google Chrome | Alt + single_character | Command + Alt + single_character | Alt + single_character |
| Mozilla Firefox | Alt + Shift + single_character | Command + Alt + single_character | Alt + Shift + single_character |
| Internet Explorer | Alt + single_character | N/A | N/A |
| Safari | Alt + single_character | Command + Alt + single_character | N/A |
| Opera | Alt + single_character | Command + Alt + single_character | Alt + single_character |
Note:
- In HTML4.1, the accesskey attributes can be used with only a few elements which include <a>, <area>, <button>, <input>, <label>, <legend>, and <textarea>.
- In HTML5, the accesskey attribute can be used with any element.
The behavior of the browser differs when dealing with more than one element having the same accesskey:
- Google Chrome and Safari: The last element with the accesskey will be activated
- Opera: The first element with the accesskey will be activated
- Internet Explorer and Mozilla Firefox: The next element with the accesskey will be activated
