Assembly: System.Windows (in System.Windows.dll)
An access key (sometimes referred to as a keyboard shortcut or mnemonic) is a character in the text of a menu, menu item, or label of a control such as a button that invokes the associated menu function. For example, to provide a shortcut way to open the File menu (for which the access key is typically F), an element might have this attached property set to "ALT+F".Notes to Inheritors
