Try this. (Not fully tested.)
Putting it in a rawKeyUp handler will also get the current word when,
for example, the delete key is pressed.
on rawKeyUp
put length(the text of me) into tLength
put word 4 of the selectedChunk into tStart
repeat with i = tStart down to 1
if char i of the text of me is in space & tab & cr or i = 1 then
put i into tP1
exit repeat
end if
end repeat
repeat with i = tStart to tLength
if char i of the text of me is in space & tab & cr or i = tLength then
put i into tP2
exit repeat
end if
end repeat
put char tP1 to tP2 of the text of me into field "debug"
pass rawKeyUp
end rawKeyUp
