markup position

[LEGRAND Jean-Marc]

Hi all of you !

I just always have the same problem : I cannot place my markups at the right 
position. My markups
are either on the top or the bottom of the stave, and I can't find out how to 
put them into the
stave itself, just like fingering with \property \Voice.fingeringOrientations 
(left), for instance.

Any help, please !
