I'm sorry if this is a duplicate post or if I am asking a question that has been asked previously, I searched for some possible topics, but I am not even sure if I am asking the right thing.
What I want to do is get into a module(s) and either correct, annotate or copy text for use in other documents. So how do I "get inside" modules?
I suppose there has to be some way of creating modules, so maybe there is a way to reverse that process. and of course I am very much interested in learning how to create and revise modules.
Thank you in advance for any assistance.
