Eclipse convert to lower or upper case

Let say you have XML and you want to change text case:

<color name="fault_list_history_item_even">#CcCcCc</color>

command+shift+x  -- UPPER CASE

  <color name="fault_list_history_item_even">#CCCCCC</color>

command+shift+y -- LOWER CASE

<color name="fault_list_history_item_even">#cccccc</color>
