Views and View Window Shortcut

Im not entirely sure if this has been discussed yet, but For me i'd love to see a shortcut combo that will maybe advance to a new view, or open the view window.

When i'm working on a PC, it becomes almost a bother to have to change views. Even when i have a single touch screen, i usually set the primary screen on it because of everything on the lower part of the screen . . . . or could we just ad a view button there when the OPEN button is pressed? :D There's pleanty of room . . .
