Hi,
I have the following string on a list box
1 2 3 4
When I click the arrow down it will go down the list in ascending order and the up arrow will go in descending order. What I want is that the down arrow would decrement the handle's value and the up arrow increment the handle's value. Is there a way to do this?
Thanks,

Maybe the question will be missinterpreted. What I really want is to scroll up with the down arrow button and scroll down with the up arrow button.

You could try using the KeyPressFcn callback: see http://www.mathworks.com/help/techdoc/ref/uicontrol_props.html#bqxoim8
