Yes, this is much nicer that the more -15 that messes up the
text with it's [MORE...] white within black. But here you can't
just tap the spacebar; is there a way around that <cr> 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, :_)
