Keyboard Maestro is a closed-source commercial Mac OS X-based application that allows automation of routine functions, such as navigating running applications, opening documents, typing text, expanding abbreviations, and controlling web applications, by means of a visual programming language with support for variables, styled clipboards, functions and text tokens, if-then-else logic, loops and other functions. Keyboard Maestro was created and first released in 2002 by Michael Kamprath and purchased by Stairways Software in 2004, and has been in continuous development since then.
