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. 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:
| Windows | Linux | Mac | |
|---|---|---|---|
| Firefox | Alt + Shift + key |
| |
| Edge | Alt + key | Control + Option + key or Control + Option + Shift + key | n/a |
| Google Chrome | Control + Option + key | ||
| Safari | n/a | Control + Option + key | |
| Opera 15+ | Alt + key | Control + Alt + key | |
| Opera 12 | Shift + Esc opens a list of available accesskeys. Choose an item from the list by pressing the key. | ||
In addition to poor browser support, there are numerous concerns with the accesskey attribute:
accesskey value 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.accesskey values may not be present on certain keyboards, especially when internationalization is a concern. So adapting to specific languages could cause further problems.accesskey values 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.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 accesskeys.Because of these issues, it is generally advised not to use accesskeys for most general-purpose websites and web apps.
