Going through a list using the minibuffer |

It is good , but I want to have something more elaborate.
Suppose I define a list namely '("alpha" "beta" "gamma")
I would like to get the minibuffer to show me the options one by
one as the down and up arrow keys are pressed. Then in my
function I get the equivalent position "k" of the string in the
list.
Thanks
