Putting text IN the staff

[Anthonys Lists]

Simple problem, I can't find the solution ... :-)

Basically, what I want is "\StaffOff   ...text...   \StaffOn". So, 
thinking treble clef, the text would be centred on the "b" line. Markup, 
however, seems to want to be above or below the staff, and that's it. 
How do I force it IN the staff, or am I using the wrong technique 
completely? I know you can force a rest to a note-position, is there any 
way of doing the same with text?

Cheers,
Wol
