 A simple, but very common usage of fld scripts: If a user selects/clicks on 
a word in the field, the script could do something to give some information
to the user about that word. In HC 2.0 this hypertext capability is extended
by "Hot Text" and "Group text style". In this way you could put the following
script into the fld: 

on mouseup
 put the clickedtext into TheString
 <do whatever you want with the text in TheString>
end mouseup

 In HC 1.* you could define clickedtext by a HT-script but it's a bit slow. You
could argue for putting this script into the cd script: OK, but then you will
end up with a very, very long and ungraspable cd script.
