⌂ Allowing fingerings to be printed inside the staff
By default, vertically oriented fingerings are positioned outside the
staff; that behavior, however, may be disabled. Attention needs to be
paid to situations where fingerings and stems are in the same direction:
by default, fingerings will avoid only beamed stems. That setting can
be changed to avoid no stems or all stems; the following example
demonstrates these two options, as well as how to go back to the
default behavior.
