Windows 7: Is there a macro key emulator?

I don't have a gaming mouse or keyboard.

So i was wondering if there is a program that allows me to hit a key, for example "5", and does an action I assigned (keystrokes, ect.) in game.

I can't really find something like it that is easy to use.

Welcome to Seven Forums Darqside. The 1st thing that comes to mind is Autohotkey. It takes some learning however, and is not just install and go, so to speak. We may have some members here who have experience using it, MilesAhead for instance has some experience, but AH also has a robust users forum

I use HotKeyz and although it does all that I require I can't truthfully say it is so easy to use. A bit of trial and error is required in safe locations to avoid disastrious results since it is quite powerful but I imagine the same can be said for most others.
