To celebrate the San Diego Comic-Con, Marvel is offering the Marvel Unlimited subscription service for $0.99 for the first month, after which it will auto-renew at the usual $9.99 per month unless you cancel. Use promo code SDCC14 when signing up through 29 July 2014. Although our in-house comic expert Josh Centers has called out issues with Marvel Unlimited’s iOS app and selection, he still believes that a subscription service makes the most sense for comic reading, and this is a great opportunity to give it a try. 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-]).
Marvel Unlimited Discounted to 99 Cents through July 29th
