I currently have a program where, by either pressing Ctrl+N or by going to "File->New" in the menu a new file is prompted.
However, there are cases in my program where I would also like the "new file" protocol to be called when a user presses a button.
Is there some way of accomplishing this, or can the "new file" protocol only be called by the standard Ctrl+N or "File->New" calls?

Thank you in advance.
