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. IE/Edge uses the first one it supports without problems, provided there are no conflicts with other commands.
The way to activate the accesskey depends on the browser and its platform:
|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
Alt + Shift + key
Control + Option + key
Control + Option + Shift + key
|Google Chrome||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|
In addition to poor browser support, there are numerous concerns with the
accesskeyvalue can conflict with a system or browser keyboard shortcut, or assistive technology functionality. What may work for one combination of operating system, assistive technology, and browser may not work with other combinations.
accesskeyvalues may not be present on certain keyboards, especially when internationalization is a concern. So adapting to specific languages could cause further problems.
accesskeyvalues that rely on numbers may be confusing to individuals experiencing cognitive concerns, where the number doesn't have a logical association with the functionality it triggers.
- Informing the user that
accesskeys are present, so that they are aware of the functionality. If the system lacks a method of notifying the user about this feature, the user might accidentally activate
Because of these issues, it is generally advised not to use
accesskeys for most general-purpose websites and web apps.
