Apple will stream its 2014 WWDC keynote on 2 June 2014 at 10 AM PDT. The video will be available in Safari on Macs running Mac OS X 10.6 Snow Leopard or later and iOS devices with iOS 4.2 or later; you can also watch on second- and third-generation Apple TVs with current software. Look for news about future versions of OS X and iOS, and potentially some hardware announcements as well. If you miss the live broadcast, the video will almost certainly be available later too. 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.
