Repeating commonly typed passages

Is there a program I can use to retpye commonly used passages (such as my e-mail address) with just one keystroke.

The simpler the better, as I don't need it to do anything too fancy.

Or maybe Windows has the capability to do this, I'm not sure.

If anyone is able to point me in the direction of what I need it would be much appreciated.

Oh, my OS is Windows Vista.
