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-]).

Speed Freaks -- Bob Nirenberg <RNIRENBE@us.oracle.com> points out a missing element in FAQtoids 001 about ISDN and serial port limitations.

I noticed you talked about the 115 Kbps limit for Mac serial port connections to ISDN, but you could have mentioned that some ISDN devices connect to your Mac via Ethernet, which relative to ISDN has unlimited capacity.

Another reader noted that you can buy and install cheap, high-speed serial cards in Macs that have card slots and achieve the same results without buying a GeoPort compatible device.
