Macworld has ended, starting out full of sound and fury (mostly sound) and draining off into the waters of Boston Harbor as everyone tried their hardest to be perky and polite when in fact they too were having trouble standing up. The weather turned out good this year, and I found the company of so many kindred spirits equally as pleasant. I enjoyed meeting many of you with whom I've spoken in the past, and I was gratified for the first time to have people stop me in the crowded aisles and thank me for TidBITS. It is I who should do the thanking since I couldn't and wouldn't do it without the many TidBITS readers. Incidentally, if you're wondering, we estimate that between 40,000 and 50,000 people read TidBITS each week. That estimate comes from readership numbers for the Usenet group comp.sys.mac.digest, our Internet mailing list, and the various commercial services. The great unknown comes from the difficult-to-track private BBSs, many of which carry TidBITS.
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-]).
