3.) Select 'Keystroke Assignment;
4.) in the resulting 'Specify Keystroke' - Keystroke window:

Explanation:Windows 8 dumped me into the old W7 desktop when I exited an application -- even if I started the application in Metro UI. Then I had to go back to keyboard to press Windows key. Now I have a mouse button to get me back to Metro UI. Editorial comment - DWJ: I think Windows 8 should default to the Metro UI upon exit from any application. After many months of objecting to Windows 8, I now like it -- but I do not like the extra key press on the Windows Key [on the keyboard] to get me back to Metro UI -- where I started. If Microsoft wants me to use the Metro UI, then Microsoft should dump me into the Metro UI whenever I exit any app.
