Uh, one more question

This is exactly what I was looking for, but with the code you gave me before, how would you set the value of the mousewheel. I am making it so depending on what CASE you entered, it will display a different array. However if you look at an array with many lines and go all the way to the bottom, then try to look at another array with less lines, you have to scroll up a lot before it will display anything. Is there a way to set the mousewheel to 0 upon opening the array? Also could you like use that value, like if you pressed "a" it would add 10 to this variable. Thanls in advance.
