The Omni Group has released OmniOutliner 4.0.5, a small maintenance release that nonetheless eases some frustration with the previous version by fixing its most frequently reported crash (which would occur randomly with any simple action). The outline and information organization app also fixes its Outline view so that rows not in the focused view are visible when switching sections, ensures that hyperlinks aren’t lost after making an edit to a row, and removes the selected state in the sidebar when you change focus. For our review, see “OmniOutliner 4 Refines the Outlining Process” (31 January 2014) ($49.99 new, free update, 45 MB, release notes, 10.9+)
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-]).
