Macworld (the publication, not the conference) covers the name change for Macworld (the conference, not the publication), talking with Macworld|iWorld’s vice president and general manager, Paul Kent. Along with the name change come some format changes, with more focus on music, art, and film. Training sessions, now called Tech Talks, now come at the lower price of $75. All in all, the changes appear to be the most significant since Apple pulled out several years ago. follow link
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-]).
