Comment 6 for bug 164140

exactt:

1. Ensure that compiz is running and that the zoom plugin is enabled (I'm not sure if it is by default, if not install compizconfig-settings-manager)
2. Start zoom by super (windows key) + mouse scroll up
3. Start switcher with alt + tab
4. Continue holding alt to keep the switcher open and pan around the screen with the mouse
5. Note that the switcher frame remains fixed (relative to the other windows), but the contents follow the mouse horizontally.
