We're back from vacation, which we enjoyed on the whole, but we could have done without the unplanned seven hour bus ride from New York City to Ithaca on a transit-style bus that could barely do 45 miles per hour on the freeway. Isn't traveling fun? For those of you making the pilgrimage to Boston in August, good luck with your flights, and I hope to see you there.
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-]).
