Question: There seems to be a lot of software to control (or emulate) mouse input through the keyboard, but what about the opposite?

Basically I'm looking for a way to emulate up/down/left/right clicks with mouse movement, at a fast rate (i.e. lots of very short and quick right clicks while I move the mouse to the right)

If I have to learn some scripting language to do it, ok, but I don't know if it would even be possible. 

Note: This is meant to work on fullscreen, and having a way to turn it on/off with an F# key would be awesome!

Thanks for your time :)

Answer: 
If you're on Windows, what about the On-Screen Keyboard?

It's found under **All Programs -> Accessories -> Accessibility** on XP (similar for Vista+)

If you want something where you can type with your mouse, then I suggest you take a look at [Dasher](http://www.inference.phy.cam.ac.uk/dasher/).

That is, if I take your question title as the question. As I really don't quite understand your question.
