The Visual Studio IDE documentation does not adequately describe all the Tools > Options... settings. In particular the documentation has paths to Reference > General user interface elements > Options > Text Editor > General. This is followed by Reference > General user interface elements > Options > Text Editor > File Extension. However, in the actual IDE, between General and File Extension, there is a dialog box for Advanced. In the Advanced dialog box, there is a dropdown ListBox called "Text formatting method" with three entries: Automatic, Ideal, and Display. I would like to know what each of those mean and how they affect the edited text.
