It's not really clear what you're trying to do; first you refer to 'where the cursor is placed', next you refer to 'from the text where it is cited'.
You could try using Find to look for '4' in the 'Endnote Reference' Style. If that's what you're after, recording the 'Find' with the macro recorder will give you the code you need.
