How can i create my scroller?

Hello guys

how r u ? hope fine

my question is that i saw a tutorial on how to do a text scroller in kirupa and i really like it , but what about if i want the scroller to be with out up arrow and down arrow , to have the ability to be scrolled up and down but the scroller itself doesnt have up and down arrow , like it may be just a small tiny rectangle or whatever, that is generally yo make ur own scroller
