Rogue Amoeba has released Fission 2.2 with support for importing more audio formats. The audio editor can now import MPEG layer 1 and 2, AIFF-C, Ogg Vorbis, Shorten, RealAudio, Windows Media Audio (WMA), AMR, QDesign Music, WavePack, and Monkey’s Audio. The update also fixes several crashes with the Batch Converter, reports file sizes in powers of ten (matching the Mac OS X Finder), removes outdated references to QuickTime importing, and now always displays the Start window at launch (and if the window is manually closed, Fission will remember not to open it until the next launch). ($32 new from Rogue Amoeba with a 20 percent discount for TidBITS members, free update, 14.3 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-]).
