The "selectedChunk" function is your friend here. Try this:

on keydown theKey
   if theKey = "*" then
     get the selectedchunk
     do "put theKey into" && it
     set the imagesource of char (word 2 of it) of me to "checkbox"
   else
     pass keydown
   end if
end keydown

You don't need a "refreshnotes" handler, just this one in the script of 
the field.
