You’ve got the whole world in your hands—or at least on your Mac—with Google Earth. Google has bumped the globetrotting software to version 6, which is now available for Intel-based Macs only. The new version adds access to a variety of views, including Street View, 3D trees, and historical imagery. Other additions include ground-level navigation, 3D measurements, and improvements to the Tour Recorder. Google Earth requires Mac OS X 10.5 Leopard or later. Note that Google Earth 6 turns out to be a beta, something that wasn't initially clear; it may be worth waiting for an official release to upgrade. (Free, 53.3 MB)
Two Shortcuts for App Exposé
If you want to see all the windows for a particular app via App Exposé, there are two hidden shortcuts. For either, start by pressing Command-Tab to bring up the app switcher. Then, while still holding down the Command key, press either the 1 key or the up arrow. That puts you into App Expose mode, with all of an app's windows showing, and recent documents in a row across the bottom of the screen. Let up on the Command key, and then you can press Tab to cycle through all the running apps.
