Google is now an automaker of sorts. It has built a prototype of its long-brewing self-driving car, which looks like a mix between a Volkswagen Beetle and a Smart Fortwo. The car features no manual controls, and, as a precaution, is limited to 25 miles per hour. Google has produced a video showing it being test-driven by a number of people — including a blind man. follow link
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.
