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-]).

 
 

GPSy 3.0 Maps New Features

Send Article to a Friend

GPSy 3.0 Maps New Features -- Directionally impaired Mac users will be relieved to learn of the release of GPSy 3.0, Karen Nakamura's software for working with data from Global Positioning System (GPS) satellites. With a GPS receiver, a Macintosh, and GPSy, you can pinpoint your location to within 100 meters anywhere on Earth (the GPS system is capable of tracking to one sixteenth of an inch, but that capability is reserved for use by the U.S. military; see Karen's article "Feeling Lost? An Overview of Global Positioning Systems," and a review, "Driving Through Trees: Using GPSy," in TidBITS-388). In addition to protocol additions for working with a wide variety of GPS units, GPSy 3.0 adds the capability to view your position using information from several Internet map servers, such as the U.S. Census TIGER Mapping Service and Geocities. GPSy is $50 and available as a 1 MB download. [JLC]
