Assembly: System.Windows (in System.Windows.dll)
Silverlight does not support accelerator keys directly. If an application responds to keyboard events to provide shortcut key behavior, it should return a string that contains the keyboard shortcut combination. For example, for an element that can copy text to the clipboard, this attached property might be set to the value "CTRL+C".
Silverlight is often hosted within a browser. The browser host might not report all possible key events to the Silverlight input system, often because the browser host might handle that key event itself. For details on this concept, see "Browser Hosts and Key Events" section of Keyboard Support.
For a list of the operating systems and browsers that are supported by Silverlight, see Supported Operating Systems and Browsers.
