Hi, I am using Word documents in a form of Karioki (Guitar - ioki) for guitar
where the guitar chords are printed above the words. the idea is as the song is
being played the scroll is started. On many songs there are repeat chorus /
interludes for instrumental solos etc. it is therefore necessary to pause / move back and alter speed, I find this difficult to control with a mouse.
what I am looking for is advice on the best way to operate auto scroll and
if using keys is an option. I have been unable to find any articles or hints on this subject so I would be grateful for any help no matter how small or trivial it may seem.

Thanks

P.S. I am 67 years old so not a computer whizz kid
