[sciurius]

QUESTION: Is there a recommended way to display the line below [Intro], recognizing each chord letter, and note the repeat, so that everything can be transposed like the rest?

[Intro]
G  G/D  <--- this works
G  G/D  x4  <--- this does not work

The easiest and straightforward way: use comments. ChordPro suppords chords in comments.

Code:

[Intro]
{comment: [G]  [G/D]  x4}

BTW I'm not sure what [intro] is supposed to mean. Is it a chord? Annotation? Comment?
