Keyboard stroke repeater program?

Alright well i dont understand how to use autoit to create a bot ( well i do im just to lazy to make a bot/ I dont need one ) I need a program that i can download and then click record ( or something along those lines ) and then have it memorize the keys i press for about the next 3~6 mins and then copy those exact keys until i tell the program to stop with a stop button. The purpose i need this for is because the thing i am doing will always be the same ( it will always be Up Up Up Up Left Left Left Bla bla bla and nothing will get in the way :P ) So err.. Yea ive seen mouse versions of it but i need a keyboard version. Thanks and im picking best answer :D!
