Use the HotSpot.AccessKey property to specify the keyboard shortcut for a System.Web.UI.WebControls.HotSpot region. This allows you to navigate quickly to the region by pressing the ALT key and the key for the specified character on the keyboard. For example, setting the access key of a System.Web.UI.WebControls.HotSpot region to the string "D" indicates that the user can navigate to the control by pressing ALT+D.

Only a single character string is allowed for the HotSpot.AccessKey property. If you attempt to set this property to a value that is neither null, string.Empty, nor a single character string, an exception is thrown.

The value of this property, when set, can be saved automatically to a resource file by using a designer tool. For more information, see System.ComponentModel.LocalizableAttribute and ASP.NET Globalization and Localization.
