Repeater

Repeater is a tool specially designed for recording and playback user actions such as mouse movements and clicks, standard and hardware keystrokes, vertical and horizontal scrolling & zooming.

It is also capable of storing information about currently running applications to launch them on playback.

Not all apps can be scripted at all, but Repeater can help you anyway.
Furthermore, you can integrate Repeater with popular scripting languages to dramatically improve their possibilities.
