We plan to test our ListSTAR-based mailing list for TidBITS in the next week (and we'll be sending the next DealBITS issue out a few days early for testing purposes), so don't worry (and please don't respond) if you get a test message from us. Also, although the new subscription address at <email@example.com> is now functional, please don't use it if you're already on the current list that we're moving from LISTSERV to ListSTAR. We will try to eliminate duplicates, but the fewer the better. [ACE]
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-]).
