Button in table to edit field in new window and than close window again

I have a table that shows active change request.

I like to add a buttom in the table that allows the reviewer to add a comment in a memo field without opening the record itself.
 currently I have this code in an URL fomula field

 URLRoot() & "db/" & Dbid() & "?a=er&key="&[Record ID#]&"&dfid=10"

and at section Display
checked --> "Open target in new Window"

This does open a new window (tab) in the browser; it does open form 10 in edit mode. So far so good.

But when I press "save&Close" on the mini-from #10 the record shows on the browser tab.
My intention is to return to the table after "save&close"

Thanks
