George,
I have the PSR2000 as well. I have had it for about 2 weeks and it is great. If you look in your manual on page 63 you can see a listing of chords. Although it does not use the (+) and (o) notation it might help in explaining which notes to press for which chords.
There is also (on page 139) a description of the Chord Tutor which might be helpful to you as well.
technicsplayer and matias had already given you the correct answer but I thought you might be interested in more feature of the 2000. I know it will take me a long while to get to every function.
Enjoy your playing. I know my wife for years has been trying to get me take Ballroom Dancing. Sounds like a fun book.

@ Big Red.

Good to know you are connected with the Holy City of Rotherham
We make the best Yorkshire puddings as well!

BTW, I looked to see where you are from but you don't say. Then I looked for other members' locations, but quite a few don't say. I always think it's nice to know who our members are and where they live, even if it's vague.
cheers
Eddie
