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-]).

 
 

Ars Technica Confirms that the $1,099 iMac Is Not a Great Deal

Send Article to a Friend

Ars Technica has benchmarked the “new” $1,099 iMac and confirmed what we initially suspected: that the money you save isn’t worth the drop in performance (see “[Apple Introduces Entry-Level iMac for $1,099][*],” 18 June 2014). In fact, for the 18 percent you save over the $1,299 iMac, you lose 50 percent of the performance, and have a machine that’s roughly equivalent in performance to a MacBook Air. However, Ars echoes what many of you told us: it’s an ideal machine for institutions that don’t need speed, but could save a fortune buying in bulk.favicon follow link
