Positive Experiences? -- Craig Isaacs <firstname.lastname@example.org> wrote to suggest that we not only talk about negative (but constructive) experiences in our Caveat Emptor column, but also positive experiences. Upon reflection, I realized that Craig raises a good point. It doesn't make the world a better place to print "I called Apple and they were nice to me." However, if you've had a positive experience with a company that will be instructive to other users, perhaps in pursuing a line of inquiry or working to fix odd bugs, and which may serve as a positive example for other companies, then publishing that information may improve the world.
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-]).
