you can use guitar-pro and do export as text. maybe powertab has the same thing?
The simplest would be notepad. The font is perfect on it and it doesn't interfere like Word.

Try and find instab, that was extremely simple but quite hard to find these days. Was a good program as well, liked it a lot.
Quote by Mia (Pulp Fiction)
Why do we feel it's necessary to yak about bullsh*t in order to be comfortable?

That's when you know you found somebody special. When you can just shut the f*ck up for a minute, and comfortably share silence.
