Fedora 15: Old and New Alt-Tab Behavior

As of Fedora 14 (Gnome 2.32) the behavior of Alt-Tab was to cycle through all the windows of all the open applications in a virtual workspace.
Gnome 3 shipping with Fedora 15 behaves differently and probably more efficiently (time will tell.)

Alt-Tab now cycles through all open applications in all virtual workspaces. All the windows of an application are shown when that application is the selected one. You can move the mouse over one window and select it but you can't just use the keyboard to do that.

If you want to cycle through all the windows of the active (selected) application you need to use Alt-~ (or the button above Tab.)

Fedora 15: Add Back Shutdown Option

Gnome 3 by default won't show the shutdown button. To see it click on your name on the top bar and press Alt. The Suspend option will turn into Power off.
If you don't want to perform this extra step (updated after kind comment):

1. Install: yum install gnome-shell-extensions-alternative-status-menu.
2. Type Alt-F2 then gnome-tweak-tool
3. Go to Shell Extensions --> Alternative Status Menu Extension and switch it to on
4. Type Alt-F2 then r and enter (reloads the Gnome shell.)
5. You're set! You have gained the Hibernate and Power off options now.

Fedora 15: Add Back Window Buttons

UPDATED on May 9, 2020

Gnome 3 default behavior suppresses all window buttons but the Close. If you want them back:

> gsettings set org.gnome.desktop.wm.preferences button-layout ":minimize,maximize,close"

or use: gnome-tweak-tool.
