That is great Peter, makes total sense :-)

For those interested in using a similar script, here is my working code, will post a copy on my site as well when I'm back in the office tonight :-)



 
var myDoc = app.activeDocument; 
var myStory = myDoc.selection[0].parentStory // active story;

// Find Strings defined 
var myFindString = "and";  //this could also be the "," character.

// Paragraph style defined. 
// Replace "YourParagraphStyleNameHere" with the exact stylename 
var myFindParaStyle = myDoc.paragraphStyles.item("YourParagraphStyleNameHere");

doFindChange(myFindString, myFindParaStyle);

// --- start function 'doFindChange' ---------------------------------------- 
function doFindChange(myFindString, myFindParaStyle) 
{ 
   app.findPreferences = null;  
   app.changePreferences = null; 



   myFindAction = myStory.search(myFindString, true, true, undefined, {appliedParagraphStyle:myFind}, undefined);

   for(i = 0; i < myFindAction.length; i++) { 

      var prevPar = myStory.paragraphs.previousItem( myFindAction[i].paragraphs[0]);

      prevPar.insertionPoints[-2].contents = "s";  
   } 
}

// --- end function ---------------------------------------------------------
