The meaning and use of this icon, as well as the compatibility mode selection in the Page menu of IE 8, is obscure. According to tooltip and help texts, clicking on the icon toggles between compatibility mode and normal mode. However, contrary to what we might expect, this is not at all the same as switching between Quirks Mode and Standards Mode.

Some features of rendering may be affected, but crucial issues such as box model are unaffected; they are based on the doctype declaration. IE 9 has seven different rendering modes, with different intermediate modes between Quirks Mode and Standards Mode.

Since the information on the mode of the shell is not available to a Web Dynpro ABAP application in the backend, you use URL parameter sap-ie to specify the preferred rendering mode.
