Variables in posts body?

Hello, thank you for your reply, I don’t know if I’ve explained my request correctly. It would naturally cover all the variables accessible to the administrator and I really think that administrators would have a great interest in having this component because it’s quite common to have to explain, for example in an administrator’s announcement category or in documentation on the site, that users can do such and such a thing depending on the values of certain variables. Obviously, the whole point of my request is that, being variables, the text presented by the administrator would be dynamic and would vary according to these variables, which if I understand your proposal correctly would not be the case for watched words and their replacement functionalities?
