I created a list with strings "1" to "5" on it. when I hit key up, must select the last cell if we are in the top... for example if current cell is in "1", hitting up will go and select "5"...

my problem is if the current cell is "1", when hit up key doesn't go to "5" as expected, it goes to "4"....any ideas, please?
