How do I remove an item from a list?

[Rosebud]

How do I remove an item from a list? For example, lets say I have a list {2,4,4,1,9,3}. How can I remove only one of the 4’s from the list? Or, how could I remove item #3 from the list? I can’t use list subtraction because it removes both 4’s from the list.
