What is a default header?
The default header is a nice feature used with new files. When you've enabled the option in the General tab (which is the default and also recommended) the piece of text you've entered here will be pasted at the top of a new file.
How do I use a default header?
This is quite easy, just type away in this window. There's no restristion in the size of the text, though you probably don't want it too big. When you use the pipe symbol ( | ) for the first time, the cursor will be placed at that point after inserting the default header.
