I am reading about this template editor and how it includes this button and that button. The first time I pressed F6 to edit the template, NotePad opened and since then I have been looking everywhere for this template editor. I assumed it is the HFS file itself, so I tried to change the editor to the HFS executable itself. I got the message 'Install this template?' after pressing F6 again to edit it.
Where is this template editor, and how can I switch from NotePad to the one that is meant to be used?
