\transposedCueDuring

[Graham Percival]

"With the command \transposedCueDuring a cue's transposition can be 
changed locally. This can be used to prevent excessive ledger lines on 
cues."


Could somebody create a short example of this so I can include it in the 
manual?  The only docs that exist for it right now is 
ly/music-functions-init.ly:
  "Insert notes from the part @var{what} into a voice called @code{cue},
using the transposition defined by @var{pitch-note}.  This happens
simultaneously with @var{main-music}, which is usually a rest.  The
argument @var{dir} determines whether the cue notes should be notated
as a first or second voice."
