Do you long for the days when your Mac would start with a smiling Mac logo and a row of INITs along the bottom of the screen? Or perhaps you miss watching a NeXT machine perform its initial memory scan? Pine no more for the past, because The Restart Page will transport you there. Choose from 17 Restart dialogs belonging to vintage versions of the Mac OS, Windows, NeXT's OPENSTEP, ProDOS (on the Apple IIgs), a developer build of Rhapsody, and others. Some sequences even include the old startup chimes.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.
