[sciurius]

If it is just the colour (or size, or font face), ChordPro has supported this for a long time:

Code:

{textcolor red}
[D]When I wake up, yeah, I know I'm gonna be,
I'm gonna [G]be the man who [A]wakes up next to [D]you.
[D]When I go out, yeah, I know I'm gonna be
{textcolor}

I assume MSPro also supports this?
