That makes sense. Just as a reminder (to others who may read this, in case you already know) EmEditor allows you to create a macro that runs an external script as well. This is a built-in feature of windows scripting host.
You can mix EmEditor macro code with the code that someone else has written so that you never have to leave the editor to do anything you want. This means you never actually have to write custom code (ulness you prefer to do so of course).
This aspect of EmEditor (direct support for windows scripting host) is really powerful, and as far as I have seen, unique for windows editors. Even editors that support macro scripting don’t usually integrate with the windows scripting host.
