Wth this answer, I tried to use jTab's custom chord syntax (ref) to display a normal chord shape with non-standard fingering. Hunting around in questions tagged
chords, the only example I found just used the bare names and let jTab implicitly select the standard shape.
So here's all the ways I tried:
In a code block
In a code block with no appended display name
In a div tag
In a div tag in a code block%3/3.2/2.0/0.0/0.3/4.3/4[G]
And I'm out of ideas. Help? Is this feature activated? Am I doing it wrong(ly)?
