RedleX has released Mellel 3.0.2, a maintenance release brimming with fixes for the word processing app. Highlights include fixes for an issue that caused the app to freeze occasionally when entering the version browser, a problem that caused some characters to appear doubled in the final citation after a bibliography scan, an issue that caused the document view to stick to the left when moving the window from screen to screen, and a problem that caused the Spotlight importer to malfunction under OS X 10.8 Mountain Lion. The release also groups palettes in a single “heap” when viewing on smaller screens (such as the 11-inch MacBook Air) and updates the application icon. ($39 new, free update, 34.9 MB, 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-]).
