View and switch between running processes while in the metro screen using only the mouse? Also, how do I close a Metro app. It takes over the whole screen with no apparent way to get out of it, I can only alt-tab or alt-f4 it. I was also wondering how I can turn my computer off via the mouse without moving the cursor to the bottom right corner, clicking settings, clicking power, clicking turn off. I am really trying to like, and even tolerate Windows 8, but the more I use it the more pissed off I am getting.
