And Then Some

Actually, despite the fact that AutoHotkey is a very simple-to-learn language, it can be much more robust and powerful if that's what you're looking for. For example, lots of Lifehacker Code projects I've written—like Texter, Swept Away, Rocker, and ClickWhen—were all created using AutoHotkey. So while you can do tons of very simple programming with AutoHotkey like creating keyboard shortcuts, you can do a lot more if you're interested. Windows automation and text replacement are also AutoHotkey fortés.

If you are interested in learning more about AutoHotkey, I'd highly recommend bookmarking the AutoHotkey commands page and visiting their forums to read up on AutoHotkey and ask questions. They're a very helpful bunch. (Thanks engunneer!)

If you're an AHK fan, let's hear what good uses you put it to in the comments.
