Objective Development has released LaunchBar 5.4.3 with improvements in detecting Google Chrome and Chromium bookmarks and with the app’s Automatic Software Update. The release also fixes an iTunes issue where the Play from Album option played only the first track, squashes a bug that caused LaunchBar not to hide after invoking a service, fixes an issue with indexing of symlinked preference panes, and ensures that dialogs don’t appear underneath the search result list. ($35 new with a 20-percent discount for TidBITS members, free update, 2.5 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-]).
