Klaus.
What are you doing here on the dark side??
Do you mean something like this, with a field and a button? in the card script:
on textChanged
set the currentText of this cd to fld 1
end textChanged
on undoText
get the currentText of this cd
delete the last word of it
set the text of fld 1 to it
set the currentText of this cd to it
end undoText
and in the button:
on mouseUp
undoText
end mouseUp
