accesskey (attribute)

The accesskey global attribute provides a hint for generating a keyboard shortcut for the current element. The attribute value must consist of a single printable character (which includes accented and other characters that can be generated by the keyboard).

Note: In the WHATWG spec it says you can specify multiple space-separated characters, and the browser will use the first one it supports. However, this does not work in most browsers. In IE/Edge it will use the first one it supports without problem, provided there are no conflicts with other commands.

The operation to activate the accesskey depends on browser and its platform.

Windows Linux Mac
Firefox Alt + Shift + key On Firefox 57 or newer, Control + Option + key -OR- Control + Alt + key
On Firefox 14 or newer, Control + Alt + key
On Firefox 13 or older, Control + key
Internet Explorer Alt + key N/A
Google Chrome Alt + key Control + Alt + key
Safari Alt + key N/A Control + Alt + key
Opera 15+ Alt + key Control + Alt + key
Opera 12

Shift + Esc opens a contents list which are accessible by accesskey, then, can choose an item by pressing key

Note that Firefox can customize the required modifier key by user's preferences.

Accessibility concerns

In addition to poor browser support, there are numerous concerns with the accesskey attribute:

  • An accesskey value can conflict with a system or browser keyboard shortcut, or assistive technology functionality. What may work for one operating system, assistive technology and browser combination may not work with others.
  • Certain accesskey values may not be present on certain keyboards, especially when internationalization is a concern.
  • accesskey values that rely on numbers may be confusing to individuals experiencing cognitive concerns, where they number does not have a logical association with the functionality it triggers.
  • Informing the user that accesskeys are present, so that they are aware of the functionality. Without a method of disclosing this information, accesskeys may be accidentally activated.

Because of these issues, it is generally advised not to use accesskey for most general-purpose websites and web apps.
