Trevor has made one at 
<http://lilypond.org/doc/v2.14/Documentation/notation/opera-and-stage-musicals> that we might want 
to include by default in LilyPond.  It is used like this:  \cueWhile "violin1" 
"strings" #UP R1

Clue clefs are rude.  LilyPond will happily set notes in the native clef of the 
instrument receiving the cue.

If the instruments are octaves apart, LilyPond will transpose

% Use this as \trCueWhile "violin1" "strings 8va" #UP c, R1
%% For 2.16 one line will need to change to
%% (string? string? ly:dir? ly:pitch? ly:music?)
trCueWhile =
#(define-music-function
   (parser location instrument name dir mc music)
   (string? string? ly:dir? ly:music? ly:music?)
    #{
      \transposedCueDuring $instrument #$dir $mc {
        \once \override TextScript #'direction = $dir
        \tag #'part s1*0-\markup { \tiny $name }
        $music
      }
    #}
  )
