xCuts is a utility for looking up Mac OS X keyboard shortcuts. Besides its comprehensive set of Mac OS X shortcuts, xCuts also covers some other applications, such as Quicksilver and Microsoft Windows.
What's new in xCuts
Fixed code that was causing xCuts to consume unnecessary CPU cycles even when idle. It should now run with 0 CPU usage when idle.
Also fixed code that made it possible to lose the bottom bar of the widget (including the drag icon) while resizing it. In the process, I made xCuts somewhat slimmer vertically.
