FearLess Cheat Engine

I can't figure out how to dupe item Plz help in "Item Pointer [view item to update]" section, it has "Dupe Item Copy Code" (wepon1984) : 1. highlight item you want to copy (for example ITEM A) 2. copy all value in "Dupe Item Copy Code" or just freeze it 3. highlight item you want to change (ITEM B)...
