Usability guru Jakob Nielsen devoted his Alertbox post this week to showing how interfaces can become confusing if elements like buttons and checkboxes are too far away from the objects they act on, using the iPhone app updating interface in iTunes as an example. Our take is that the overall mistake here is that Apple is relying on iTunes for too many unrelated tasks that call out for different interface approaches. 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-]).
