x-ms-acceleratorKey attribute | x-ms-acceleratorKey property
Provides a way to declare that an accelerator key has been assigned to an element.
<element x-ms-acceleratorKey="string" ... >
Name of accelerator key, for example: Ctrl+B or Ctrl+S.
There are no standards that apply here.
The x-ms-acceleratorKey attribute enables you to expose a notification in the accessibility tree to screen readers and other assistive technologies that an accelerator key exists. This attribute does not provide the accelerator key behavior. You must provide keyboard event handlers, such as onkeypress, onkeydown, or onkeyup, to process accelerator keys in your document.
In contrast to accessKey, which defines Alt+key shortcuts to UI elements in your interface, the x-ms-acceleratorKey attribute assigns keyboard shortcuts to functionality and commands for which you might not even have UI. Accelerator keys consist of the Ctrl key and a letter.
