Tonya was one for two last week. Her expose of space aliens calling technical support brought in reprint requests from three continents (and yes, please feel free to reprint that article as long as you credit Tonya and TidBITS fully, and please send us a copy of the publication - use the address at the end of the issue). At the same time, her article on the AV Macs had a few mistakes, which we correct below. We also hope to have some detailed first hand reports soon, which should help you decide for yourself about these fascinating Macs. Hey, I want one.
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-]).
