CopyDoubler details were lousy in last week's review. We gave the wrong AOL address and upgrade price. Sigh, that's what happens when you believe a database. The real AOL address is FIFTHGEN@aol.com and the upgrade price should be $19.95. If you snag the demo copy, which only works for three weeks, it includes an offer for $19.95 that's good until 31-Dec-93, which is the cheapest way to get CopyDoubler if you can't upgrade.
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-]).
