Performa Service -- Apple recently reminded dealers that Performa owners are welcome to bring their computers to "regular" Macintosh dealers should they need repair, in or out of warranty. This option could be handy for people who live or work near an Apple dealer but who can't wait at home all day for an in-home service technician to arrive. Machines brought in for warranty repair will need to be accompanied by proof-of-purchase date.
Go Back and Forth Fast in Preview
If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.
The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).
