ExecCommand exposes a large array of commands for which there are no methods exposed on HtmlDocument. Using ExecCommand you can insert new HTML elements, select and format text, and clear any cached authentication credentials. For a full list of commands, see Command Identifiers.


Certain commands, such as copy, have return values. In the current implementation of ExecCommand, you cannot obtain a return value from your call. To retrieve return values, use the corresponding unmanaged method on a DomDocument reference instead.
