Access Keys and Keyboard Navigation

C1WebCommand2 supports access and shortcut keys for all of its controls to make its controls more accommodating for all types of users. Access keys are used for navigating the entire user interface and typically use the Alt key plus the specified access key. Shortcut keys are commonly used to perform a quick action such as opening a menu item and they use the Ctrl key plus the specified shortcut key.

By default the KeyboardSupport property is set to True to enable keyboard control of the selected control. To use keyboard navigation effectively, you can use the TAB key to tab to set the focus for the desired control. Pressing the TAB key gets the standard input focus appearance for the control which is a dotted line around the inner border of the item in the control. Once the focus is set, you can navigate through the element by using its associated keyboard shortcuts.

You can apply shortcut keys by specifying the string for the shortcut key in the KeyboardShortcut. To enhance the user experience in your Web application you can display the shortcut keys next to each item by setting the ShowKeyboardShortCuts property to True.
