Switch Between The Same Windows Of The Focused Application Using A Keyboard Shortcut [Quick Linux w/ Compiz Tip]

Ever since we wrote about the very simple Pidgin/Empathy script to focus the conversation window using a keyboard shortcut, I've been trying (together with WebUpd8 reader RKV) to create a similar script using xdotool for switching between the same windows of the currently focused (active) application: kind of like an ALT + TAB but for an application only (for example: all opened Nautilus windows, all opened OpenOffice Word Processor opened files, etc.). But there's no need of a script after all, as it seems Compiz can do much more things than I could imagine, and comes with an option for the behavior I was telling you about above.
