Rollover> Programed animation

Ive got a question here.
Ive got a drawing on stange, and i got an arrow there to. And some buttons. When i roll over one button, id like the arrow to go to a sertain poit on the drawing. And then, regardless og what point the arrow was at, id like it to go straigt to the next point when you roll over another button.

Basicly, id like it to go straight from point 4 to point 8 without any other.

Anyone know how or what im talkin about?
