Operate is an action used on items. The operate function is only usable on an item that is equipped.
Operate usually only works on items that are either enchanted, non-tradeable or quest-related like the following:
What it works on
Enchanted items | Non-tradeable items | Quest-related | Special items |
---|---|---|---|
Amulet of Magic | Explorer's ring | Cape of accomplishment | |
Amulet of glory | Ava's Accumulator | Skull Sectre |
Existence
The action 'Operate' still exists on some items, but some have been changed from rub or operate to something more specific. Take, for example, an Amulet of glory. When right clicking the amulet, while being equipped, it lists the destinations instead of the usual "operate".
Operating
In certain quests and occasions, you may have to operate a machine or sceneric tool. E.g. In 2008's Easter event when you had to operate the incubator.
