Chords

Hi,

I'm trying to find out how to regarding to write guitar chords, how i'm able to tell to play an upstroke and/or downstroke?

Searched everywhere, but can't find it....

Hope you can help.

Kind regards,

(For your information I am from Holland and I have the Dutch version of your program and I would be very much obliged if you can (also) give me the Dutch instruction (or if you are not able to provide, just in English. I'm happy with all assistance... ;) )
