PF Auto-Typer is a simple program that simulates key presses on your computer while the focus is on another application. It reads a text file, and recopy its content into any active typing field with some given options such as delay, loop, etc. You can use PF Auto-Typer to send fake messages to your friends on an instant messenger, or for custom uses. Messages are separated by a new line in the text file, so an enter key press will be simulated at the end of each line. It also has a built-in programming language, the PFATL, to extend the possibilities (execute files, control the mouse, display messages, etc.).
