Accidental text in score

[Terje Tjervaag]

Hi,

Sorry if this is covered in the manual, I can't find it anywhere.  Is 
it possible to insert pieces of text anywhere within the score?  I'm 
thinking about comments and whatnot and it would be useful to be able 
to place them wherever.  If this is not possible, what are the 
possibilities in Lilypond regarding comments and other information 
along the lines of the score?

I also have a question about fingering information.  Is it possible to 
have two sets of fingering informations, one above and one below the 
lines to signify the left and right hand respectively?  And is it 
possible to replace the numbers in the fingering notation by letters so 
t=thumb, i=index and so on?

Thanks!
