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)
Option-Click in Scroll Bars for Jump Scrolling
In Mac OS X in general, and thus in most native Mac OS X applications, hold down the Option key and click anywhere in a window's scroll bar to jump to that spot (rather than scrolling one screen). If you like this behavior, you can make it the default in the Appearance preference pane. For "Click in the scroll bar to:" select "Jump to here."
