Hi, can I _exclude_ categories from replace.py? I mean it has -cat/-catr/-subcats/-subcatsr for working within a category. But I want to use it everywhere BUT in a given category end its subcats. Or could anyone write this feature? The task is: changing o/O letters following a digit to 0 (zero). This is a frequent error. But I don't work in Chemistry and subcats, because there is more often on purpose. -- Bináris
