The latest versions of SmileOnMyMac's PDF editing utilities PDFpen and PDFpenPro bring a handful of minor, but appreciated, tweaks. Changes include better text selection and highlighting in scanned documents through better position accuracy, improved compatibility with sheet-fed scanners, the resolution of a bug that prevented text annotations from being drawn, and the capability to select text in fonts with zero ascent and descent. The updates also bring several other unspecified bug fixes and improvements. ($49.95/$99.95 new, free updates, 45.9 MB/46.1 MB)
How to Make an iPhone Screenshot
Want to take a screenshot of something on your iPhone or iPod touch? Press the Home button and Power button briefly at the same time, and an image of your screen will be saved to the Photos app (and will sync with iPhoto when you next connect). Don't hold the buttons too long or your device will either power down or reboot.
