Mac OS X 10.1.3 Released -- Apple has released the Mac OS X 10.1.3 update as a 17.3 MB download via Software Update. (If you're running Mac OS X 10.1 or 10.1.1, a separate 38.4 MB combined update to 10.1.3 is available.) As with previous updates to Mac OS X, this one is well worth getting, and kudos to Apple for providing decent release notes. Along with reliability improvements, Mac OS X 10.1.3 includes more drivers for CD burners and digital cameras, enables DVD playback on external VGA displays connected to PowerBook G4s, turns video mirroring on by default when a PowerBook connects to a new display, and offers improvements to iTunes with full screen visualizers. Networking security received attention as well, with login authentication support for LDAP and Active Directory services, an update to OpenSSH 3.0.2p1, WebDAV support for Digest authentication, and support for SSL encryption in Apple's Mail application.

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-]).
