But here you can't just tap the spacebar; is there a way around that and turning it into a space...? Also, can you insert "^+++" text "^+++" top And bottom? Pretty sure that the user would have the large font to read aloug with that espeak read to hijm. Having the top/bottom delimiters might make scanning the text easier. (It messed up with more. Anyway, thanks foe something that actually works, :_) gary -- Gary Kline kline@thought.org http://www.thought.org Public Service Unix Journey Toward the Dawn, E-Book: http://www.thought.org The 7.98a release of Jottings: http://jottings.thought.org
