edit: script for editing metadata in Adobe Bridge - how should I put "Key Words" (separate words) into code?

Question

I have a simple script for editing metadata in Adobe Bridge with find and replace functionality. It is for Description section only.

I need to make it work for Keywords section only instead. I tried to change description into keywords (with and without Description > Keywords), but the end result is the script which doesn't work. What (else) needs to be changed or added in order to achieve what I need?

edit:

I tried to change description into title to make the script work for the Title section and it worked.

So the question is what exactly should replace description to make this work for the Keywords section?

I saw in one script that for Bridge it should be Key Words (separate), so if that's the case, how should I write that in the code? (yes, I'm a noob in javascript)

I've found a different script which provides the functionality I need, and even better since it gives the option to add and remove keywords:

#target bridge  

   if( BridgeTalk.appName == "bridge" ) {  
keyReplace = MenuElement.create("command", "Add-Replace-Remove Keyword", "at the end of tools");
}
keyReplace.onSelect = function () { 
      mainReplaceKeyword();
      }

function mainReplaceKeyword(){
if(app.version.substr(0,app.version.indexOf('.'))==1){
alert("Sorry You Need CS3 or CS4 to run this script!"); 
return;
    }
var dlg =
