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-]).

 
 

OS X Yosemite’s Handoff Will Require Bluetooth 4.0

Send Article to a Friend

Handoff will be one of the coolest features of OS X Yosemite and iOS 8, letting you seamlessly transition between workflows on the two platforms, but unfortunately for owners of older Macs, it will require Bluetooth 4.0, which excludes Macs built before 2011, and even many built later. Peter Cohen of iMore explains how to check which version of Bluetooth your Mac has. If your Mac isn’t compatible with Handoff, a USB dongle that provides Bluetooth 4.0 may enable Handoff by Yosemite’s release.favicon follow link

Not totally clear yet that a USB Bluetooth 4 dongle will work - see the comments to Peter's piece. I hope it will, as all of our machines are pre-BT 4.0 Macbook Pros, recently upgraded with extra RAM and SSDs - no plans to get new machines, but would hate to miss out on this feature.
