AirPort 3.1 Supports Third Party 802.11g PC Cards -- Owners of pre-AirPort Extreme PowerBooks with PC Card slots can now connect to higher-speed AirPort Extreme networks using third-party 802.11g cards. It turns out that Apple's recent AirPort 3.1 update also provides support for PC Cards that use the same Broadcom chip set that Apple uses for internal AirPort Extreme cards. So, if you've been lamenting the poor signal strength of your Titanium PowerBook G4, you can improve signal strength and jump up to 802.11g's faster throughput with a third party card. Both Asante and Buffalo Technologies claim their 802.11g cards work with Mac OS X and the AirPort 3.1 update; other manufacturers using Broadcom's chip set are likely compatible as well. Buffalo Technology's card costs about $60 and is available now; the Asante card costs $100 and should be available this month. [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-]).
