Hey, I also just installed / upgraded to gnome3 and have run into some strange problems with keyboard navigation. First off, I cannot get into the desktop; also I can't find a reliable way to get into the system menu. Keep in mind here, I'm totally blind and do not use the mouse. I rely strictly on use of the keyboard to navigate around the environment. With gnome2, one can use Ctrl+Alt+d to open the desktop from anywhere in gnome and the system menu was simply part of the main menu structure. Now the application and places menus are side by side but no system menu. Also, the key combination to focus the desktop doesn't work. In fact, when I use the Ctrl+Alt+Tab key combination to cycle focus between the top and botom panels, there is no desktop there either. In gnome2, the desktop was also included in that rotation. Any ideas on how to fix this? Is this another sign of broken functionality in gnome3?
