Something like this, maybe (untested)
on mouseup
put word 2 of of the clickCharChunk into chNbr
put the number of words of char 1 to chNbr of me \
into wordNbr
put the formattedheight of word 1 to wordNbr of me \
into upToHere
put the textheight of me into txtHt
set the scroll of me to upToHere - txtHt
-- so the line remains visible
end mouseup
