(Up) button
This button, and the (Down) button, let you control the order information will be printed.
Click this button to move the selected item up (to the next higher position in the list). File information is printed in the order in which it appears in this list. So moving an item up means it will appear earlier in the line printed for a particular file.
Tip: You can press <Ctrl>+<Up Arrow>, after selecting the entry to move, instead of clicking the Up button.
