Keyboard automation

Does anyone know of a good, but simple program that will record keystrokes and repeat them when called by keyboard shortcuts? Essentially I want to setup a script that will repeat a couple keystrokes until I stop the script. I'm not sure how to do this with applescript. I just recently purchased my Mac and I love it, but I'm still learning.

Also does anyone know if there's a site out there that describes applescript and keyboard commands; maybe a list of all the commands to perform the same thing I'm trying to accomplish above?
