Mouseover effect on FAQ page needed.

I am doing a FAQ html page .
I want to place the Questions on the left side of page IE
Q1
Q2
Q3


The effect I'm after is when the Mouse is over say Q1 The Answers appear on the right side of the html page.

I want the Answer to be easly editable as it will be changed regularly

Is there a script that will do this ??

any help please.
