True.  Even then, the usual workflow would involve a writing phase, and
formatting phase guided by visual feedback.

I find in the menu under the chapter "Staff symbol" an example

It is apparent that modifying the line count to 3 will not change the
vertical position of the notes.  The clef/note relation is not disturbed
by the number of lines apparently.

The question is whether the text should be more explicit for visually
impaired readers (which actually include all persons with a text
browser, or using standalone info without image support).

Does braille output have the equivalent of lines?
