Do it again, Sam!

Do it again is a simple macro/automation program.

As the developers (spacetornado) puts it:
"Do It Again is a free and simple program that allows you to make your computer automatically perform a task for you, whenever you want."

Sometimes handsfree computing is what you need.
Try to macro that Facebook game overnight!

There are other, more sophisticated programs, and even simpler ones.
Will mention 2 i came to think about the next days.
