peter It's more for when using PDFs rather than lyrics. I do use timers for lyrics and chord sheets as you suggest but when trying to follow a solo on a PDF such as Santana's Smooth, i need to look away to the neck in some places and if I don't look back at the right place, it's easy to mess up. I just wonder if a scrolled PDF could have the previous part 'greyed' or something so that the eye doesn't go back to the wrong line, especially when it has moved half a page. I'll try to make a screenshot later in the week when I'm at home to show you what I mean.
