Annotation text file double spaced

When I create an annotation text file, the default is to double space, or at least not single space. I can’t seem to find where to change this - even on a file by file basis. I can change the font etc, but not the line spacing. I’m opening the file in DT.

Is there a way to do this by default, or perhaps just on a file by file basis?

Thanks in advance.

The spacing isn’t double-spaced, but there’s a larger space between paragraphs than between lines within a paragraph.

You may modify spacing via the Space item in the Toolbar.
