Poll Preview: Keeping It to Yourself -- The news media has lately been replete with stories detailing threats to consumer privacy: every day we hear about employers scanning company email, sites tracking every movement of users (and some advertising services tracking users' movements between sites!), or miscreants gaining access to home computers by guessing at an all-too-predictable password. So, this week our poll asks whether you use any specific tactics to protect your privacy online. Responses include using strong (not easily guessed) passwords, blocking or auditing cookies Web sites want to give you, using anonymous email or Web services, or using encryption to protect your data. Vote on our home page - and, yes, our polls are anonymous! [GD]
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-]).
