 ## Command experiences using the XamlUICommand class
 
-If you need to create a command that isn't defined by the [StandardUICommand](/windows/windows-app-sdk/api/winrt/microsoft.ui.xaml.input.standarduicommand) class, or you'd like more control over the command appearance, the [XamlUiCommand](/windows/windows-app-sdk/api/winrt/microsoft.ui.xaml.input.xamluicommand) class derives from the [ICommand](/windows/windows-app-sdk/api/winrt/microsoft.ui.xaml.input.icommand) interface, adding various UI properties (such as an icon, label, description, and keyboard shortcuts), methods, and events to quickly define the UI and behavior of a custom command.

 [XamlUICommand](/windows/windows-app-sdk/api/winrt/microsoft.ui.xaml.input.xamluicommand) lets you specify UI through the control binding, such as an icon, label, description, and keyboard shortcuts (both an access key and a keyboard accelerator), without setting the individual properties.
