iKey is a utility that can eliminate repetitive actions. iKey allows creation of shortcuts that perform an action or sequence of actions each of which can be launched by key combinations, menu, timer, event or USB devices. Save time, typing and hundreds of clicks everyday. Avoid carpal tunnel, do less and accomplish more. An excellent manual written by Adam Engst is included.
