Retrospect and Retrospect Express 4.3 Released -- Dantz Development has released version 4.3 of both their Retrospect and Retrospect Express backup programs, adding support for numerous USB and FireWire storage devices and erasing the 2 GB limit on file backup sets when used with Mac OS 9 or later on HFS Plus-formatted hard disks. In addition, Retrospect Express gains the capability to store multiple incremental backups to a single file on a secondary hard disk, something previously available only in the more-expensive Retrospect. (Keep in mind that relying on single backup on an external hard disk isn't an ideal backup strategy.) Upgrades for Retrospect users are available as a 14 MB free download (the Retrospect Client update is included); upgrades for Retrospect Express users cost $10 for a downloadable version or $20 for a CD-ROM with Mac OS 9.0.4 that can boot all current Macs. Both versions require a Mac running System 7 or later with at least 16 MB of RAM. [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-]).
