Objective Development has released LaunchBar 5.4.2 with improvements in indexing actions, services, and applications for the keyboard-based launcher. In addition to an overall performance boost to LaunchBar’s indexing engine, the update now recognizes executable shell scripts more reliably (even if they have filename extensions), ignores iOS apps when indexing applications, and improves 1Password indexing (especially on systems with multiple installed versions of 1Password). The release also replaces the previously used generic category icons in iTunes (Albums, Genres, Playlists, etc.) with dedicated icons, and it fixes a problem with the Play from Album option that started playing from the beginning of the album rather than the selected track. Finally, LaunchBar 5.4.2 fixes a bug with determining the originator of a copy operation when triggered with a mouse click (instead of pressing Command-C), an issue with sending a labeled email address via Instant Send, and the appearance of double quotes in conjunction with Instant Send or Clipboard History.

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-]).
