what is wrong with this \markup /padding?

[Jay Hamilton, Sound and Silence]

I think I've copied (retyped) it from the manual.

\once \override TextScript #'padding = 2.0
\markup{ \italic Moderato }

All I am attemptin is to get the word Moderato higher above the notes of 
the staff.

the response I get is

C:/Documents and Settings/Owner/Desktop/NoteWorthy/nwc files/Guitar/Oud 
bk 2 line 94-224/Oud 129-132.ly:27:40: error: syntax error, unexpected '.'
\once \override TextScript #'padding = 2
                                       .0

C:/Documents and Settings/Owner/Desktop/NoteWorthy/nwc files/Guitar/Oud 
bk 2 line 94-224/Oud 129-132.ly:28:9: error: unknown escaped string: 
`\italic'
\markup{
        \italic Moderator }

So what am I doing wrong?
Thank you.
