Comment 1 for bug 842137

The pattern to follow here I believe is hit the top left edge of the screen, buttons appear (if you click on the top left edge window should close, thats not the case yet but will be soon, so closing a window will be faster than ever) and then you move the mouse to the desired control. Once the "Average" user first discover these controls he wont forget where they are, there are also things planned to improve the discoverability of those buttons and menus.
