Youpi Key is a keyboard macro and task automation tool by developer Philippe Hupe. I'm a big fan of keyboard macro programs, they allow me to optimize some of the eccentricities I can't seem to shake, like manually typing in "http://" into every browser's location field. Youpi Key version 1.7.5 includes a number of bug fixes, as well as some new features for OS X 10.2 like window manipulation. And best of all: it's freeware.
