 Removing @code{Staff_symbol_engraver} also hides bar lines.  If
 bar line visibility is forced, formatting errors may occur.  In
 this case, use the following overrides instead of removing the
 engraver:

-\override StaffSymbol #'stencil = ##f

+
+Like @code{\quoteDuring}, @code{\cueDuring} takes instrument
+transpositions into account.  Cue notes are produced at the

+to produce the sounding pitches of the source instrument.
+
+To transpose cue notes differently, use

+represent the sound of a concert middle C.  This is useful for
+taking cues from an instrument in a completely different register.
