	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, :_)
