Showing up/down arrows in cells

Hi. I am trying to edit the template file of stock performance found here on Microsoft.com
http://office.microsoft.com/sv-se/te...tier&av=TPL000


In the file there is field for profit/loss (called vinst / förlust in this swedish translation) and to the left of the numbers it shows a green up arrow if it is a profit and red down arrow for a loss.

where in excel do you turn it on or off this function that shows up and down arrows, depending on the value... or is it some specific coded function for this template?

thx in advance
