Adobe has released Illustrator CS6 16.0.1 with a number of fixes to improve overall stability. The update resolves an issue with Illustrator unexpectedly quitting if you have only read-only permissions on the Preferences folder, ensures the Transform commands work as expected when using the Transform Patterns option, fixes the Save for Web command to correctly create images with specified dimensions, and more. Additionally, the new release should improve copying and pasting when working with a third-party clipboard manager. ($599 new, $249 upgrade, free update, 5.8 MB via direct download, release notes)
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-]).
