Thanks for the reply.  The contents are a single field.  There's only 
one card, and the index field and contents field are about all there 
is.  Just a title and a 'put away' button.  The script for the index 
field is:

on mouseup
   put the value of the clickline into tFindText
   if  tFindText contains "overview" then find "overview" in fld 
"contents"
   else find whole tFindText in fld "contents"
end mouseup

The index is generated by hand.  It's not a big deal, but when the last 
foundchunk (or line) is somewhere in the middle or near the bottom and 
a line in the index field that is above the last one is clicked, 
nothing happens.  It takes a second click for it to do anything.  I was 
hoping there was a tip someone could offer to script around that.
