Tabs for ASP.NET Web Forms features keyboard support for the C1Tabs control and each of its tab pages. You can enable this feature for the whole tabstrip by setting the C1Tabs.AccessKey property to an access key, or you can enable this feature for individual tabs by setting the C1TabPage.AccessKey property to an access key. Once the AccessKey property is set, you can access an element by pressing the ALT key and the access key simultaneously on your keyboard.
