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)
Type an em-dash on an iPhone
Typography and punctuation geeks rejoice! It's easy to type an em-dash on the iPhone's or iPod touch's virtual keyboard. To do so, tap the .?123 key to switch to the numeric keypad. Then touch and hold on the Hyphen key to reveal a pop-up strip showing an em-dash. Slide to the em-dash and release your finger.
Note that this basic trick works with many other keys on the virtual keyboard.
