Opening a URL in Adobe Captivate and have it then go back to the Parent tab

Hi,

I was hoping someone could tell me what the Advance Action code is to open a URL (I have that part :)) but, then have it go back to the parent tab as I am afraid the user will get lost, but of course, leave the tab window there. Would it help to open it in a new window instead? Any information on this subject matter would be greatly appreciated. 

Sincerely,

Suzi
