Have you ever selected a bunch of files and accidentally opened them all by double-clicking one? Or perhaps inadvertently pressed Command-I to get info, ending up with oodles of open Info windows? Here’s a quick way to recover. You can close all the windows in any well-written app with judicious use of the Option key. Press it while clicking the File menu and Close Window becomes Close All Windows. Command-W closes one window; Command-Option-W closes all of that app’s windows. If you’re a mouse person, Option-click the red close button in any window to close all the rest.
